 NewPipe contribution guidelines
 ===============================

-PLEASE READ THESE GUIDELINES CAREFULLY BEFORE ANY CONTRIBUTION!
-
 ## Crash reporting

-Do not report crashes in the GitHub issue tracker. NewPipe has an automated crash report system that will ask you to
-send a report via e-mail when a crash occurs. This contains all the data we need for debugging, and allows you to even
-add a comment to it. You'll see exactly what is sent, the system is 100% transparent.
+Report crashes through the **automated crash report system** of NewPipe.
+This way all the data needed for debugging is included in your bugreport for GitHub.
+You'll see *exactly* what is sent, be able to add **your comments**, and then send it.

 ## Issue reporting/feature requests

-* Search the [existing issues](https://github.com/TeamNewPipe/NewPipe/issues) first to make sure your issue/feature
-hasn't been reported/requested before.
-* Check whether your issue/feature is already fixed/implemented.
-* Check if the issue still exists in the latest release/beta version.
-* If you are an Android/Java developer, you are always welcome to fix an issue or implement a feature yourself. PRs welcome!
-* We use English for development. Issues in other languages will be closed and ignored.
-* Please only add *one* issue at a time. Do not put multiple issues into one thread.
-* Follow the template! Issues or feature requests not matching the template might be closed.
+* **Already reported**? Browse the [existing issues](https://github.com/TeamNewPipe/NewPipe/issues) to make sure your issue/feature hasn't been reported/requested.
+* **Already fixed**? Check whether your issue/feature is already fixed/implemented.
+* **Still relevant**? Check if the issue still exists in the latest release/beta version.
+* **Can you fix it**? If you are an Android/Java developer, you are always welcome to fix an issue or implement a feature yourself. PRs welcome! See [Code contribution](#code-contribution) for more info.
+* **Is it in English**? Issues in other languages will be ignored unless someone translates them.
+* **Is it one issue**? Multiple issues require multiple reports, that can be linked to track their statuses.
+* **The template**: Fill it out, everyone wins. Your issue has a chance of getting fixed.

-## Bug Fixing
-* If you want to help NewPipe to become free of bugs (this is our utopic goal for NewPipe), you can send us an email to
-<a href="mailto:tnp@newpipe.schabi.org">tnp@newpipe.schabi.org</a> to let us know that you intend to help. We'll send you further instructions. You may, on request,
-register at our [Sentry](https://sentry.schabi.org) instance (see section "Crash reporting" for more information).

 ## Translation

-* NewPipe is translated via [Weblate](https://hosted.weblate.org/projects/newpipe/strings/). You can log in there
-with your GitHub account.
-* If the language you want to translate is not on Weblate, you can add it: see [How to add a new language](https://github.com/TeamNewPipe/NewPipe/wiki/How-to-add-a-new-language-to-NewPipe) in the wiki.
+* NewPipe is translated via [Weblate](https://hosted.weblate.org/projects/newpipe/strings/). Log in there with your GitHub account, or register.
+* Add the language you want to translate if it is not there already: see [How to add a new language](https://github.com/TeamNewPipe/NewPipe/wiki/How-to-add-a-new-language-to-NewPipe) in the wiki.

 ## Code contribution

-* Stick to NewPipe's style conventions: follow [checkStyle](https://github.com/checkstyle/checkstyle). It will run each time you build the project.
-* Do not bring non-free software (e.g. binary blobs) into the project. Also, make sure you do not introduce Google
-  libraries.
+### Guidelines
+
+* Stick to NewPipe's *style conventions* of [checkStyle](https://github.com/checkstyle/checkstyle) and [ktlint](https://github.com/pinterest/ktlint). They run each time you build the project.
 * Stick to [F-Droid contribution guidelines](https://f-droid.org/wiki/page/Inclusion_Policy).
-* Make changes on a separate branch with a meaningful name, not on the master neither dev branch. This is commonly known as *feature branch workflow*. You
-  may then send your changes as a pull request (PR) on GitHub.
-* When submitting changes, you confirm that your code is licensed under the terms of the
-  [GNU General Public License v3](https://www.gnu.org/licenses/gpl-3.0.html).
-* Please test (compile and run) your code before you submit changes! Ideally, provide test feedback in the PR
-  description. Untested code will **not** be merged!
+* In particular **do not bring non-free software** (e.g. binary blobs) into the project. Make sure you do not introduce any closed-source library from Google.
+
+### Before starting development
+
+* If you want to help out with an existing bug report or feature request, **leave a comment** on that issue saying you want to try your hand at it.
+* If there is no existing issue for what you want to work on, **open a new one**  describing the changes you are planning to introduce. This gives the team and the community a chance to give **feedback** before you spend time on something that is already in development, should be done differently, or should be avoided completely.
+* Please show **intention to maintain your features** and code after you contribute a PR. Unmaintained code is a hassle for core developers. If you do not intend to maintain features you plan to contribute, please rethink your submission, or clearly state that in the PR description.
+* Create PRs that cover only **one specific issue/solution/bug**. Do not create PRs that are huge monoliths and could have been split into multiple independent contributions.
+* NewPipe uses [NewPipeExtractor](https://github.com/TeamNewPipe/NewPipeExtractor) to fetch data from services. If you need to change something there, you must test your changes in NewPipe. Telling NewPipe to use your extractor version can be accomplished by editing the `app/build.gradle` file: the comments under the "NewPipe libraries" section of `dependencies` will help you out.
+
+### Kotlin in NewPipe
+* NewPipe will remain mostly Java for time being
+* Contributions containing a simple conversion from Java to Kotlin should be avoided. Conversions to Kotlin should only be done if Kotlin actually brings improvements like bug fixes or better performance which are not, or only with much more effort, implementable in Java. The core team sees Java as an easier to learn and generally well adopted programming language.
+
+### Creating a Pull Request (PR)
+
+* Make changes on a **separate branch** with a meaningful name, not on the _master_ branch or the _dev_ branch. This is commonly known as *feature branch workflow*. You may then send your changes as a pull request (PR) on GitHub.
+* Please **test** (compile and run) your code before submitting changes! Ideally, provide test feedback in the PR description. Untested code will **not** be merged!
+* Respond if someone requests changes or otherwise raises issues about your PRs.
 * Try to figure out yourself why builds on our CI fail.
-* Make sure your PR is up-to-date with the rest of the code. Often, a simple click on "Update branch" will do the job,
-  but if not, you are asked to rebase the dev branch manually and resolve the problems on your own. You can find help [on the wiki](https://github.com/TeamNewPipe/NewPipe/wiki/How-to-merge-a-PR). That will make the
-  maintainers' jobs way easier.
-* Please show intention to maintain your features and code after you contributed it. Unmaintained code is a hassle for
-  the core developers, and just adds work. If you do not intend to maintain features you contributed, please think again
-  about submission, or clearly state that in the description of your PR.
-* Respond yourselves if someone requests changes or otherwise raises issues about your PRs.
-* Send PR that only cover one specific issue/solution/bug. Do not send PRs that are huge and consists of multiple
-  independent solutions.
+* Make sure your PR is **up-to-date** with the rest of the code. Often, a simple click on "Update branch" will do the job, but if not, you must *rebase* your branch on the `dev` branch manually and resolve the conflicts on your own. You can find help [on the wiki](https://github.com/TeamNewPipe/NewPipe/wiki/How-to-merge-a-PR). Doing this makes the maintainers' job way easier.
+
+## IDE setup & building the app
+
+### Basic setup
+
+NewPipe is developed using [Android Studio](https://developer.android.com/studio/). Learn more about how to install it and how it works in the [official documentation](https://developer.android.com/studio/intro). In particular, make sure you have accepted Android Studio's SDK licences. Once Android Studio is ready, setting up the NewPipe project is fairly simple:
+- Clone the NewPipe repository with `git clone https://github.com/TeamNewPipe/NewPipe.git` (or use the link from your own fork, if you want to open a PR).
+- Open the folder you just cloned with Android Studio.
+- Build and run it just like you would do with any other app, with the green triangle in the top bar.
+
+You may find [SonarLint](https://www.sonarlint.org/intellij)'s **inspections** useful in helping you to write good code and prevent bugs.
+
+### checkStyle setup
+
+The [checkStyle](https://github.com/checkstyle/checkstyle) plugin verifies that Java code abides by the project style. It runs automatically each time you build the project. If you want to view errors directly in the editor, instead of having to skim through the build output, you can install an Android Studio plugin:
+- Go to `File -> Settings -> Plugins`, search for `checkstyle` and install `CheckStyle-IDEA`.
+- Go to `File -> Settings -> Tools -> Checkstyle`.
+- Add NewPipe's configuration file by clicking the `+` in the right toolbar of the "Configuration File" list.
+- Under the "Use a local Checkstyle file" bullet, click on `Browse` and pick the file named `checkstyle.xml` in the project's root folder.
+- Enable "Store relative to project location" so that moving the directory around does not create issues.
+- Insert a description in the top bar, then click `Next` and then `Finish`.
+- Activate the configuration file you just added by enabling the checkbox on the left.
+- Click `Ok` and you are done.
+
+### ktlint setup
+
+The [ktlint](https://github.com/pinterest/ktlint) plugin does the same job as checkStyle for Kotlin files. Installing the related plugin is as simple as going to `File -> Settings -> Plugins`, searching for `ktlint` and installing `Ktlint (unofficial)`.

+
+## Installación y actualizaciones
+Se puede instalar NewPipe usando uno de los métodos siguientes:
+ 1. Agregar nuestro repositorio personalizado a F-Droid e instalarlo desde allí. Las instrucciones están aquí: https://newpipe.net/FAQ/tutorials/install-add-fdroid-repo/
+ 2. Descargar el archivo APK del enlace [Github Releases](https://github.com/TeamNewPipe/NewPipe/releases) e instalarlo.
+ 3. Actualizar a través de F-Droid. Este es el método más lento para obtener la actualización, como F-Droid debe reconocer cambios, construir el APK aparte, firmarlo con una clave, y finalmente empujar la actualización a los usuarios.
+ 4. Construir un APK de depuración por si mismo. Este es el modo más rápido para realizar nuevas características en su dispositivo, pero es mucho más complicado, asi que recomendamos uno de los otros métodos.
+
+Recomendamos el método 1 para la mayoría de usuarios. Los APKs instalados usando método 1 o 2 son compatibles el uno con el otro, pero no con las instalaciones usando método 3. Esta es debida a la misma clave digital (la nuestra), siendo utilizado en los métodos 1 y 2, pero una clave digital diferente (la de F-Droid) siendo utilizado en el método 3. Construir un APK de depuración usando método 4 excluye una clave enteramente. Firmando con claves  digitales ayuda a asegurar de que un
+usuario no esté engañado para instalar una actualización maliciosa a una app. 
+
+Mientras tanto, si quiere cambiar los fuentes por alguna razón (por ejemplo, la funcionalidad del nucleo de NewPipe se rompe y F-Droid aun no tiene la actualización), recomendamos el siguiente procedimiento:
+1. Repaldear sus datos a través de Ajustes > Contenido > Exporta base de datos para guardar su historia, subscripciones, y listas de reproducción
+2. Desinstalar NewPipe
+3. Descargar el APK del nuevo fuente e instalarlo.
+4. Importar los datos del paso 1 a través de Ajustes > Contenido > Importa base de datos.
+

+## インストールと更新
+以下の方法のいずれかに従うことによって NewPipe をインストールできます。
+1. カスタムリポジトリを F-Droid に追加してリリースが公開され次第インストールする。この方法の説明はこちら: https://newpipe.net/FAQ/tutorials/install-add-fdroid-repo/
+2. リリースが公開され次第[GitHub のリリース](https://github.com/TeamNewPipe/NewPipe/releases)から APK をダウンロードしてインストールする。
+3. F-Droid から更新する。これは更新を手にする上で最も遅い方法です。F-Droid が変更を検知して、APK をビルドし、署名、そしてユーザーに更新を届ける必要があるためです。
+4. 自分でデバッグ APK をビルドする。これは新しい機能を使用する上で最も早い方法ですが、他と比べてとても複雑なので、他の方法の使用を推奨します。
+
+私たちはほとんどのユーザーに方法1を推奨します。方法1と2でインストールされた APK は互換性がありますが、方法3でインストールされたものにはありません。これは方法1と2では、同じ署名鍵 (私たちが使用するもの)が使用されますが、方法3では異なった署名鍵 (F-Droidが使用するもの)が使用されるためです。方法4を使ったデバッグ APK のビルドは根本的に署名鍵の問題を除きます。署名鍵はユーザーが騙されて悪意のある更新がアプリにインストールされないことを助けるためにあります。
+
+もし、何かしらの理由によりソースを切り替えたい場合 (例: NewPipe のコア機能が壊れてしまったが F-Droid はまだ更新をしていない) は、この手順を推奨します。
+1. 履歴や登録チャンネル、再生リストを保つために 設定 > コンテンツ > データベースをエクスポート からデータをバックアップ
+2. NewPipe をアンインストール
+3. 新しいソースから APK をダウンロードしてインストール
+4. 設定 > コンテンツ > データベースをインポート からステップ1で作ったデータベースをインポート

+## Description
+
+NewPipe는 어떤 구글 프레임워크 라이브러리나, 유튜브 API를 사용하지 않습니다. 웹사이트는 단지 필요한 정보를 가져오기 위해 구문 분석 됩니다. 따라서 이 앱은 구글 서비스의 설치 없이 기기에서 사용될 수 있습니다. 또한, 카피레프트 자유 소프트웨어인 NewPipe를 사용하기 위해 유튜브 계정이 필요하지 않습니다.

+
+## Updates
+NewPipe 코드의 변경이 있을 때(기능 추가 또는 버그 수정으로 인해), 결국 릴리즈가 발생할 것입니다. 이것들의 형식은 x.xx.x 입니다. 
+이 새로운 버전을 얻기 위해서, 당신은:
+ 1. 직접 디버그 APK를 생성할 수 있습니다. 이 방법은 당신의 기기에서 새로운 기능을 얻을 수 있는 가장 빠른 방법이지만, 꽤 많이 복잡합니다.
+ 따라서 우리는 다른 방법들 중 하나를 사용하는 것을 추천합니다.
+ 2. 우리의 커스텀 저장소를 F-Droid에 추가하고 우리가 릴리즈를 게시하는 대로 저곳에서 릴리즈를 설치할 수 있습니다. 
+ 이에 대한 설명서는 이곳에서 확인할 수 있습니다: https://newpipe.net/FAQ/tutorials/install-add-fdroid-repo/
+ 3. 우리가 릴리즈를 게시하는 대로 [Github Releases](https://github.com/TeamNewPipe/NewPipe/releases)에서 APK를 다운받고 이것을 설치할 수 있습니다.
+ 4. F-Droid를 통해 업데이트 할 수 있습니다. F-Droid는 변화를 인식하고, 스스로 APK를 생성하고, 이것에 서명하고, 사용자들에서 업데이트를 전달해야만 하기 때문에,
+ 이것은 업데이트를 받는 가장 느린 방법입니다.
+
+우리는 대부분의 사용자에게 2번쨰 방법을 추천합니다. 방법 2 또는 3을 사용하여 설치된 APK는 서로 호환되지만, 방법 4를 사용하여 설치된 것들과는 호환되지 않습니다. 이것은 방법 2 또는 3에서는 같은 (우리의)서명 키가 사용되지만, 방법 4에서는 다른 (F-Droid의)서명 키가 사용되기 때문입니다. 방법 1을 사용하여 디버그 APK를 생성하는 것에서는 키가 완전히 제외됩니다. 서명 키는 사용자가 앱에 악의적인 업데이트를 설치하는 것에 대해 속지 않도록 보장하는 것을 도와줍니다.
+
+한편, 만약 어떠한 이유(예. NewPipe의 핵심 기능이 손상되었고 F-Droid가 아직 업데이트를 가지지 않는 경우) 때문에 소스를 바꾸길 원한다면, 
+우리는 다음과 같은 절차를 따르는 것을 권장합니다:
+1. 당신의 기록, 구독, 그리고 재생목록을 유지할 수 있도록 Settings > Content > Export Database 를 통해 데이터를 백업하십시오.
+2. NewPipe를 삭제하십시오.
+3. 새로운 소스에서 APK를 다운로드하고 이것을 설치하십시오.
+4. Step 1의 Settings > Content > Import Database 을 통해 데이터를 불러오십시오.

-## Updates
-When a change to the NewPipe code occurs (due to either adding features or bug fixing), eventually a release will occur. These are in the format x.xx.x . In order to get this new version, you can:
- * Build a debug APK yourself. This is the fastest way to get new features on your device, but is much more complicated, so we recommend using one of the other methods.
- * Download the APK from [releases](https://github.com/TeamNewPipe/NewPipe/releases) and install it.
- * Update via F-droid. This is the slowest method of getting updates, as F-Droid must recognize changes, build the APK itself, sign it, then push the update to users.
+<!-- Hidden span to keep old links compatible. -->
+<span id="updates"></span>

-When you install an APK from one of these options, it will be incompatible with an APK from one of the other options. This is due to different signing keys being used. Signing keys help ensure that a user isn't tricked into installing a malicious update to an app, and are independent. F-Droid and GitHub use different signing keys, and building an APK debug excludes a key. The signing key issue is being discussed in issue [#1981](https://github.com/TeamNewPipe/NewPipe/issues/1981), and may be fixed by setting up our own repository on F-Droid.
+## Installation and updates
+You can install NewPipe using one of the following methods:
+ 1. Add our custom repo to F-Droid and install it from there. The instructions are here: https://newpipe.net/FAQ/tutorials/install-add-fdroid-repo/
+ 2. Download the APK from [Github Releases](https://github.com/TeamNewPipe/NewPipe/releases) and install it.
+ 3. Update via F-Droid. This is the slowest method of getting updates, as F-Droid must recognize changes, build the APK itself, sign it, then push the update to users.
+ 4. Build a debug APK yourself. This is the fastest way to get new features on your device, but is much more complicated, so we recommend using one of the other methods.

-In the meanwhile, if you want to switch sources for some reason (e.g. NewPipe's core functionality was broken and F-Droid doesn't have the update yet), we recommend following this procedure:
-1. Back up your data via "Settings>Content>Export Database" so you keep your history, subscriptions, and playlists
+We recommend method 1 for most users. APKs installed using method 1 or 2 are compatible with each other, but not with those installed using method 3. This is due to the same signing key (ours) being used for 1 and 2, but a different signing key (F-Droid's) being used for 3. Building a debug APK using method 4 excludes a key entirely. Signing keys help ensure that a user isn't tricked into installing a malicious update to an app.

+
+## Atualizações
+Quando uma alteração no código NewPipe (devido à adição de recursos ou fixação de bugs), eventualmente ocorrerá uma versão. Estes estão no formato x.xx.x . A fim de obter esta nova versão, você pode:
+ 1. Construa um APK de depuração você mesmo. Esta é a maneira mais rápida de obter novos recursos em seu dispositivo, mas é muito mais complicado, por isso recomendamos usar um dos outros métodos.
+ 2. Adicione nosso repo personalizado ao F-Droid e instale-o a partir daí assim que publicarmos um lançamento. As instruções estão aqui.: https://newpipe.net/FAQ/tutorials/install-add-fdroid-repo/
+ 3. Baixe o APK do [Github Releases](https://github.com/TeamNewPipe/NewPipe/releases) e instalá-lo assim que publicarmos um lançamento.
+ 4. Atualização via F-droid. Este é o método mais lento para obter atualizações, pois o F-Droid deve reconhecer alterações, construir o próprio APK, assiná-lo e, em seguida, enviar a atualização para os usuários.
+
+Recomendamos o método 2 para a maioria dos usuários. Os APKs instalados usando o método 2 ou 3 são compatíveis entre si, mas não com aqueles instalados usando o método 4. Isso se deve à mesma chave de assinatura (nossa) sendo usada para 2 e 3, mas uma chave de assinatura diferente (F-Droid's) está sendo usada para 4. Construir um APK depuração usando o método 1 exclui totalmente uma chave. Assinar chaves ajudam a garantir que um usuário não seja enganado para instalar uma atualização maliciosa em um aplicativo.
+
+Enquanto isso, se você quiser trocar de fontes por algum motivo (por exemplo, a funcionalidade principal do NewPipe foi quebrada e o F-Droid ainda não tem a atualização), recomendamos seguir este procedimento:
+1. Faça backup de seus dados através de Configurações > Conteúdo > Exportar Base de Dados para que você mantenha seu histórico, inscrições e playlists
+2. Desinstale o NewPipe
+3. Baixe o APK da nova fonte e instale-o
+4. Importe os dados da etapa 1 via Configurações > Conteúdo > Inportar Banco de Dados

+
+## Instalare şi actualizări
+Puteţi instala NewPipe folosind una dintre următoarele metode:
+ 1. Adăugaţi depozitul nostru F-droid personalizat. Instrucţiunile sunt aici: https://newpipe.net/FAQ/tutorials/install-add-fdroid-repo/
+ 2. Descărcaţi APK-ul din [Github Releases](https://github.com/TeamNewPipe/NewPipe/releases) şi instalaţi-l.
+ 3. Actualizaţi via F-Droid. Aceasta este cea mai lentă metodă de a obţine actualizări, deoarece F-Droid trebuie să recunoască schimbările, să constriască APK-ul, să îl semneze, iar apoi să îl trimită utilizatorilor.
+ 4. Construiţi un APK de depanare. Aceasta este cea mai rapidă metodă de a primi funcţii noi, dar este mult mai complicată, aşa că vă recomandăm să folosiţi una dintre celelalte metode.
+
+Recomandăm metoda 1 pentru majoritatea utilizatorilor. APK-urile din metodele 1 şi 2 suntcompatibile una cu cealaltă, dar nu cu cele din metoda 3. Acest lucru se datorează faptului că aceeași cheie de semnare (a noastră) este utilizată pentru 1 și 2, dar o altă cheie de semnare (F-Droid) este utilizată pentru 3. Construirea unui APK de depanare folosind metoda 4 exclude o cheie în întregime. Cheile de semnare vă asigură că un utilizator nu este păcălit să instaleze o actualizare rău intenționată a unei aplicații.
+
+Între timp, dacă doriți să schimbați sursa dintr-un anumit motiv (de exemplu, funcționalitatea de bază a NewPipe a fost întreruptă și F-Droid nu are încă actualizarea), vă recomandăm să folosiţi următoarea procedură:
+1. Faceți o copie de rezervă a datelor prin Setări> Conținut> Exportați baza de date, astfel încât să vă păstrați istoricul, abonamentele și playlisturile
+2. Dezinstalaţi NewPipe
+3. Descărcaţi APK-ul din noua sursă şi instalaţi-l
+4. Importați datele de la pasul 1 prin Setări> Conținut> Importare bază de date
+

+
+### Adeegyada la Taageero
+
+NewPipe wuxuu taageeraa adeegyo badan. [warqadan](https://teamnewpipe.github.io/documentation/) ayaa si faahfaahsan u sharaxaysa sida adeeg cusub loogu soo dari lahaa iyo kala fur-furaha. Fadlan nala soo xidhiidh hadaad rabto inaad mid cusub kusoo darto. Adeegyada aan hadda taageero waxaa kamid ah:
+
+* YouTube
+* SoundCloud \[tijaabo\]
+* media.ccc.de \[tijaabo\]
+* PeerTube instances \[tijaabo\]
+* Bandcamp \[tijaabo\]
+
+## Kushubida iyo cusboonaysiinta
+Marka koodhka NewPipe isbadal ku dhaco (wax cusub oo lagusoo kordhiyay ama cilad bixin), ugu dambayn waxaa lasii daayaa mid cusub (Siidayn). Siidaynta qaabkeedu waa x.xx.x . Si aad midka cusub u hesho, waxaad samayn kartaa:
+ 1. Inaad mid cusub (APK) adigu dhisato. Tani waa mida ugu dagdag badan eed waxyaabaha cusub ku heli karto, laakiin way adagtahay, sidaa darteed waxaan soojeedinaynaa inaad isticmaasho qababka kale.
+ 2. Ku dar qayb gaar ah xaganaga F-Droid oo xagaas kaga shub isla markay siidayn soobaxdo. Hagitaanka xagan ka eeg: https://newpipe.net/FAQ/tutorials/install-add-fdroid-repo/
+ 3. Kasoo dajiso APK-ga xaga [Siidaynta Github](https://github.com/TeamNewPipe/NewPipe/releases) oo ku shubo isla markay siidayn soobaxdo.
+ 4. Ka cusboonaysii xaga F-Droid. Tani waa mida ugu daahitaanka badan, sababtoo ah F-Droid waxay fiirin isbadalka waxayna iyadu dhisi mid (app), sixiixi, kadibna ay cusboonaysiinta usiidayn isticmaalayaasha.
+
+Waxaan usoojeedinaynaa isticmaaalka qaabka 2 dadka badankood. APK-yada loogu shubo qaabka 2 ama 3 way isqaadan karaan, laakiin isma qaadan karaan kuwa loogu shubay qaabka 4. Sababtuna waxaa weeye furaha sixiixa oo iskumid ah (kaanaga weeye) oo loo isticmaalay 2 iyo 3, laakiin furo sixiixeed ka duwan (midka F-Droid) oo loo isticmaalay 4. Dhisida APK ayadoo la isticmaalayo qaabka 1 waxay gabi ahaanba ka reebtaa wax fure ah. Furayaasha sixiixa waxay xaqiijiyaan in isticmaalaha aan lagu khaldin inuu ku shubto cusboonaysiin khalad ah (wax lasoo dhexraaciyay) app-ka.
+
+Waxaa kale, hadaad rabto inaad tixraacayada kala badasho sabab jirta awgeed (tusaale shaqaynta aasaasiga ah ee NewPipe ayaa khalkhashay F-Droid-na wali cusboonysiin ma hayo), waxaan soojeedinaynaa isticmaalka qaabkan:
+1. Xogtaada koobi ka samee adoo raacaya Fadhiga > Luuqada & Fadhiga Kale > Gudbi Xog Diyaaran si aysa kaaga bixin kaydka wixii hore, rukunka, iyo xulalka
+2. Saar NewPipe
+3. Kasoo daji APK-ga tixraaca cusub oo ku shub
+4. Kasoo gali xogta talaabada 1 xaga Fadhiga > Luuqada & Fadhiga Kale >  Soo Gali Xog Kaydsan
+
+## Kusoo Kordhin
+Hadaad hayso fikrado; rogid, qaab badal, nadiifin koodh, ama koodhka ood si wayn wax oga badashaa—caawinta marwalba waa lasoo dhawaynayaa. Waxbadan hadii la qabto waxbadan ayaa fiicnaan!

+
+## Kurulum ve güncellemeler
+Aşağıdaki yöntemlerden birini kullanarak NewPipe'ı kurabilirsiniz:
+ 1. Özel depomuzu F-Droid'e ekleyin ve oradan yükleyin. Kılavuzu şurada bulabilirsiniz: https://newpipe.net/FAQ/tutorials/install-add-fdroid-repo/
+ 2. APK'yı [Github sürümlerinden](https://github.com/TeamNewPipe/NewPipe/releases) indirin ve kurun.
+ 3. F-Droid ile güncelleyin. Bu, güncellemeleri almanın en yavaş yöntemidir, çünkü F-Droid değişiklikleri tanımalı, APK'yı kendisi oluşturmalı, imzalamalı ve ardından güncellemeyi kullanıcılara dağıtmalıdır.
+ 4. Kendiniz bir APK derleyin. Bu yöntem, cihazınızda yeni özellikler edinmenin en hızlı yoludur, ancak çok daha karmaşıktır, bu nedenle diğer yöntemlerden birini kullanmanızı öneririz.
+
+Çoğu kullanıcı için yöntem 1'i öneririz. Yöntem 1 veya 2 kullanılarak yüklenen APK'lar birbiriyle uyumludur, ancak yöntem 3 kullanılarak yüklenenlerle uyumlu değildir. Bu durum, 1 ve 2 için kullanılan aynı imzalama anahtarıın (bizim anahtarımız) 3 için kullanılan imzalama anahtarından (F-Droid'in anahtarı) farklı olmasından kaynaklanmaktadır. Yöntem 4 kullanılarak oluşturulan deneysel APK'larda anahtar yoktur. İmzalama anahtarları, bir kullanıcının bir uygulamaya kötü amaçlı bir güncelleme yüklemek için kandırılmadığından emin olmanıza yardımcı olur.
+
+Bu arada, herhangi bir nedenle kaynakları değiştirmek istiyorsanız (örneğin, NewPipe'ın temel bir işlevi bozuldu ve F-Droid tarafında henüz bir güncelleme yayınlanmadı), bu prosedürü izlemenizi öneririz:
+1. Verilerinizi yedekleyin. `NewPipe Ayarları > İçerik > Veritabanını dışa aktar` seçeneklerini izleyerek aboneliklerinizi, oynatma listelerinizi ve geçmişinizi yedekleyin.
+2. NewPipe'ı kaldırın
+3. APK dosyasını yeni bir kaynaktan indirin ve yükleyin
+4. `Ayarlar > İçerik > Veritabanını içe aktar` seçeneklerini izleyerek 1. adımdaki verileri içe aktarın

+
+<p>THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS ECLIPSE
+    PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR
+    DISTRIBUTION OF THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS
+    AGREEMENT.</p>
+
+<p><b>1. DEFINITIONS</b></p>
+
+<p>"Contribution" means:</p>
+
+<p class="list">a) in the case of the initial Contributor, the initial
+    code and documentation distributed under this Agreement, and</p>
+<p class="list">b) in the case of each subsequent Contributor:</p>
+<p class="list">i) changes to the Program, and</p>
+<p class="list">ii) additions to the Program;</p>
+<p class="list">where such changes and/or additions to the Program
+    originate from and are distributed by that particular Contributor. A
+    Contribution 'originates' from a Contributor if it was added to the
+    Program by such Contributor itself or anyone acting on such
+    Contributor's behalf. Contributions do not include additions to the
+    Program which: (i) are separate modules of software distributed in
+    conjunction with the Program under their own license agreement, and (ii)
+    are not derivative works of the Program.</p>
+
+<p>"Contributor" means any person or entity that distributes
+    the Program.</p>
+
+<p>"Licensed Patents" mean patent claims licensable by a
+    Contributor which are necessarily infringed by the use or sale of its
+    Contribution alone or when combined with the Program.</p>
+
+<p>"Program" means the Contributions distributed in accordance
+    with this Agreement.</p>
+
+<p>"Recipient" means anyone who receives the Program under
+    this Agreement, including all Contributors.</p>
+
+<p><b>2. GRANT OF RIGHTS</b></p>
+
+<p class="list">a) Subject to the terms of this Agreement, each
+    Contributor hereby grants Recipient a non-exclusive, worldwide,
+    royalty-free copyright license to reproduce, prepare derivative works
+    of, publicly display, publicly perform, distribute and sublicense the
+    Contribution of such Contributor, if any, and such derivative works, in
+    source code and object code form.</p>
+
+<p class="list">b) Subject to the terms of this Agreement, each
+    Contributor hereby grants Recipient a non-exclusive, worldwide,
+    royalty-free patent license under Licensed Patents to make, use, sell,
+    offer to sell, import and otherwise transfer the Contribution of such
+    Contributor, if any, in source code and object code form. This patent
+    license shall apply to the combination of the Contribution and the
+    Program if, at the time the Contribution is added by the Contributor,
+    such addition of the Contribution causes such combination to be covered
+    by the Licensed Patents. The patent license shall not apply to any other
+    combinations which include the Contribution. No hardware per se is
+    licensed hereunder.</p>
+
+<p class="list">c) Recipient understands that although each Contributor
+    grants the licenses to its Contributions set forth herein, no assurances
+    are provided by any Contributor that the Program does not infringe the
+    patent or other intellectual property rights of any other entity. Each
+    Contributor disclaims any liability to Recipient for claims brought by
+    any other entity based on infringement of intellectual property rights
+    or otherwise. As a condition to exercising the rights and licenses
+    granted hereunder, each Recipient hereby assumes sole responsibility to
+    secure any other intellectual property rights needed, if any. For
+    example, if a third party patent license is required to allow Recipient
+    to distribute the Program, it is Recipient's responsibility to acquire
+    that license before distributing the Program.</p>
+
+<p class="list">d) Each Contributor represents that to its knowledge it
+    has sufficient copyright rights in its Contribution, if any, to grant
+    the copyright license set forth in this Agreement.</p>
+
+<p><b>3. REQUIREMENTS</b></p>
+
+<p>A Contributor may choose to distribute the Program in object code
+    form under its own license agreement, provided that:</p>
+
+<p class="list">a) it complies with the terms and conditions of this
+    Agreement; and</p>
+
+<p class="list">b) its license agreement:</p>
+
+<p class="list">i) effectively disclaims on behalf of all Contributors
+    all warranties and conditions, express and implied, including warranties
+    or conditions of title and non-infringement, and implied warranties or
+    conditions of merchantability and fitness for a particular purpose;</p>
+
+<p class="list">ii) effectively excludes on behalf of all Contributors
+    all liability for damages, including direct, indirect, special,
+    incidental and consequential damages, such as lost profits;</p>
+
+<p class="list">iii) states that any provisions which differ from this
+    Agreement are offered by that Contributor alone and not by any other
+    party; and</p>
+
+<p class="list">iv) states that source code for the Program is available
+    from such Contributor, and informs licensees how to obtain it in a
+    reasonable manner on or through a medium customarily used for software
+    exchange.</p>
+
+<p>When the Program is made available in source code form:</p>
+
+<p class="list">a) it must be made available under this Agreement; and</p>
+
+<p class="list">b) a copy of this Agreement must be included with each
+    copy of the Program.</p>
+
+<p>Contributors may not remove or alter any copyright notices contained
+    within the Program.</p>
+
+<p>Each Contributor must identify itself as the originator of its
+    Contribution, if any, in a manner that reasonably allows subsequent
+    Recipients to identify the originator of the Contribution.</p>
+
+<p><b>4. COMMERCIAL DISTRIBUTION</b></p>
+
+<p>Commercial distributors of software may accept certain
+    responsibilities with respect to end users, business partners and the
+    like. While this license is intended to facilitate the commercial use of
+    the Program, the Contributor who includes the Program in a commercial
+    product offering should do so in a manner which does not create
+    potential liability for other Contributors. Therefore, if a Contributor
+    includes the Program in a commercial product offering, such Contributor
+    ("Commercial Contributor") hereby agrees to defend and
+    indemnify every other Contributor ("Indemnified Contributor")
+    against any losses, damages and costs (collectively "Losses")
+    arising from claims, lawsuits and other legal actions brought by a third
+    party against the Indemnified Contributor to the extent caused by the
+    acts or omissions of such Commercial Contributor in connection with its
+    distribution of the Program in a commercial product offering. The
+    obligations in this section do not apply to any claims or Losses
+    relating to any actual or alleged intellectual property infringement. In
+    order to qualify, an Indemnified Contributor must: a) promptly notify
+    the Commercial Contributor in writing of such claim, and b) allow the
+    Commercial Contributor to control, and cooperate with the Commercial
+    Contributor in, the defense and any related settlement negotiations. The
+    Indemnified Contributor may participate in any such claim at its own
+    expense.</p>
+
+<p>For example, a Contributor might include the Program in a commercial
+    product offering, Product X. That Contributor is then a Commercial
+    Contributor. If that Commercial Contributor then makes performance
+    claims, or offers warranties related to Product X, those performance
+    claims and warranties are such Commercial Contributor's responsibility
+    alone. Under this section, the Commercial Contributor would have to
+    defend claims against the other Contributors related to those
+    performance claims and warranties, and if a court requires any other
+    Contributor to pay any damages as a result, the Commercial Contributor
+    must pay those damages.</p>
+
+<p><b>5. NO WARRANTY</b></p>
+
+<p>EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS
+    PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS
+    OF ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION,
+    ANY WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY
+    OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely
+    responsible for determining the appropriateness of using and
+    distributing the Program and assumes all risks associated with its
+    exercise of rights under this Agreement , including but not limited to
+    the risks and costs of program errors, compliance with applicable laws,
+    damage to or loss of data, programs or equipment, and unavailability or
+    interruption of operations.</p>
+
+<p><b>6. DISCLAIMER OF LIABILITY</b></p>
+
+<p>EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT
+    NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,
+    INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING
+    WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
+    LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING
+    NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR
+    DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED
+    HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.</p>
+
+<p><b>7. GENERAL</b></p>
+
+<p>If any provision of this Agreement is invalid or unenforceable under
+    applicable law, it shall not affect the validity or enforceability of
+    the remainder of the terms of this Agreement, and without further action
+    by the parties hereto, such provision shall be reformed to the minimum
+    extent necessary to make such provision valid and enforceable.</p>
+
+<p>If Recipient institutes patent litigation against any entity
+    (including a cross-claim or counterclaim in a lawsuit) alleging that the
+    Program itself (excluding combinations of the Program with other
+    software or hardware) infringes such Recipient's patent(s), then such
+    Recipient's rights granted under Section 2(b) shall terminate as of the
+    date such litigation is filed.</p>
+
+<p>All Recipient's rights under this Agreement shall terminate if it
+    fails to comply with any of the material terms or conditions of this
+    Agreement and does not cure such failure in a reasonable period of time
+    after becoming aware of such noncompliance. If all Recipient's rights
+    under this Agreement terminate, Recipient agrees to cease use and
+    distribution of the Program as soon as reasonably practicable. However,
+    Recipient's obligations under this Agreement and any licenses granted by
+    Recipient relating to the Program shall continue and survive.</p>
+
+<p>Everyone is permitted to copy and distribute copies of this
+    Agreement, but in order to avoid inconsistency the Agreement is
+    copyrighted and may only be modified in the following manner. The
+    Agreement Steward reserves the right to publish new versions (including
+    revisions) of this Agreement from time to time. No one other than the
+    Agreement Steward has the right to modify this Agreement. The Eclipse
+    Foundation is the initial Agreement Steward. The Eclipse Foundation may
+    assign the responsibility to serve as the Agreement Steward to a
+    suitable separate entity. Each new version of the Agreement will be
+    given a distinguishing version number. The Program (including
+    Contributions) may always be distributed subject to the version of the
+    Agreement under which it was received. In addition, after a new version
+    of the Agreement is published, Contributor may elect to distribute the
+    Program (including its Contributions) under the new version. Except as
+    expressly stated in Sections 2(a) and 2(b) above, Recipient receives no
+    rights or licenses to the intellectual property of any Contributor under
+    this Agreement, whether expressly, by implication, estoppel or
+    otherwise. All rights in the Program not expressly granted under this
+    Agreement are reserved.</p>
+
+<p>This Agreement is governed by the laws of the State of New York and
+    the intellectual property laws of the United States of America. No party
+    to this Agreement will bring a legal action under this Agreement more
+    than one year after the cause of action arose. Each party waives its
+    rights to a jury trial in any resulting litigation.</p>

-<p>
-Version 2, June 1991
-</p>
-
-<pre>
-Copyright (C) 1989, 1991 Free Software Foundation, Inc.<br/>
-51 Franklin Street, Fifth Floor, Boston, MA  02110-1301, USA<br/>
-<br/>
-Everyone is permitted to copy and distribute verbatim copies
-of this license document, but changing it is not allowed.
-</pre>
-
-<h3 id="preamble"><a id="SEC2">Preamble</a></h3>
-
-<p>
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.)  You can apply it to
-your programs, too.
-</p>
-
-<p>
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-</p>
-
-<p>
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-</p>
-
-<p>
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-</p>
-
-<p>
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-</p>
-
-<p>
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-</p>
-
-<p>
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-</p>
-
-<p>
-  The precise terms and conditions for copying, distribution and
-modification follow.
-</p>
-
-
-<h3 id="terms"><a id="SEC3">TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</a></h3>
-
-
-<p id="section0">
-<strong>0.</strong>
- This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-</p>
-
-<p>
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-</p>
-
-<p id="section1">
-<strong>1.</strong>
- You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-</p>
-
-<p>
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-</p>
-
-<p id="section2">
-<strong>2.</strong>
- You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-</p>
-
-<dl>
-  <dt></dt>
-    <dd>
-      <strong>a)</strong>
-      You must cause the modified files to carry prominent notices
-      stating that you changed the files and the date of any change.
-    </dd>
-  <dt></dt>
-    <dd>
-      <strong>b)</strong>
-      You must cause any work that you distribute or publish, that in
-      whole or in part contains or is derived from the Program or any
-      part thereof, to be licensed as a whole at no charge to all third
-      parties under the terms of this License.
-    </dd>
-  <dt></dt>
-    <dd>
-      <strong>c)</strong>
-      If the modified program normally reads commands interactively
-      when run, you must cause it, when started running for such
-      interactive use in the most ordinary way, to print or display an
-      announcement including an appropriate copyright notice and a
-      notice that there is no warranty (or else, saying that you provide
-      a warranty) and that users may redistribute the program under
-      these conditions, and telling the user how to view a copy of this
-      License.  (Exception: if the Program itself is interactive but
-      does not normally print such an announcement, your work based on
-      the Program is not required to print an announcement.)
-    </dd>
-</dl>
-
-<p>
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-</p>
-
-<p>
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-</p>
-
-<p>
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-</p>
-
-<p id="section3">
-<strong>3.</strong>
- You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-</p>
-
-<!-- we use this doubled UL to get the sub-sections indented, -->
-<!-- while making the bullets as unobvious as possible. -->
-
-<dl>
-  <dt></dt>
-    <dd>
-      <strong>a)</strong>
-      Accompany it with the complete corresponding machine-readable
-      source code, which must be distributed under the terms of Sections
-      1 and 2 above on a medium customarily used for software interchange; or,
-    </dd>
-  <dt></dt>
-    <dd>
-      <strong>b)</strong>
-      Accompany it with a written offer, valid for at least three
-      years, to give any third party, for a charge no more than your
-      cost of physically performing source distribution, a complete
-      machine-readable copy of the corresponding source code, to be
-      distributed under the terms of Sections 1 and 2 above on a medium
-      customarily used for software interchange; or,
-    </dd>
-  <dt></dt>
-    <dd>
-      <strong>c)</strong>
-      Accompany it with the information you received as to the offer
-      to distribute corresponding source code.  (This alternative is
-      allowed only for noncommercial distribution and only if you
-      received the program in object code or executable form with such
-      an offer, in accord with Subsection b above.)
-    </dd>
-</dl>
-
-<p>
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major softwareComponents (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-</p>
-
-<p>
-If distribution of executable or object code is made by offering

-<strong>4.</strong>
- You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.

-<p id="section5">
-<strong>5.</strong>
- You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-</p>
-
-<p id="section6">
-<strong>6.</strong>
- Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.

-<p id="section7">
-<strong>7.</strong>
- If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.

-<p>
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.

-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.

-<p id="section8">
-<strong>8.</strong>
- If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.

-<p id="section9">
-<strong>9.</strong>
- The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-</p>
-
-<p>
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-</p>
-
-<p id="section10">
-<strong>10.</strong>
- If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.

-<p id="section11"><strong>NO WARRANTY</strong></p>
