 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.

+* 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
 
-* If you want to add a feature or change one, please open an issue describing your change. This gives the team and community a chance to give feedback before you spend any time on something that could be done differently or not done at all. It also prevents two contributors from working on the same thing and one being disappointed when only one user's code can be added.
-* 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
+* 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 your changes. 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.
+* Stick to NewPipe's style conventions of [checkStyle](https://github.com/checkstyle/checkstyle). It runs each time you build the project.
+* Do not bring non-free software (e.g. binary blobs) into the project. Make sure you do not introduce Google
   libraries.
 * 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!
+* 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!
+* 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 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 makes the maintainers' jobs way easier.
+* 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.
+* Respond if someone requests changes or otherwise raises issues about your PRs.
+* Send PRs that only cover one specific issue/solution/bug. Do not send PRs that are huge and consist of multiple independent solutions.
 * Try to figure out yourself why builds on our CI fail.

-* If you want to get in touch with the core team or one of our other contributors you can send an email to
-  <a href="mailto:tnp@newpipe.schabi.org">tnp@newpipe.schabi.org</a>. Please do not send issue reports, they will be ignored and remain unanswered! Use the GitHub issue
-  tracker described above!
-* Feel free to post suggestions, changes, ideas etc. on GitHub or IRC!

+
+## 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

-## 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:
- 1. 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.
- 2. Add our custom repo to F-Droid and install it from there as soon as we publish a release. The instructions are here: https://newpipe.schabi.org/FAQ/tutorials/install-add-fdroid-repo/
- 3. Download the APK from [Github Releases](https://github.com/TeamNewPipe/NewPipe/releases) and install it as soon as we publish a release.
- 4. 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>
 
-We recommend method 2 for most users. APKs installed using method 2 or 3 are compatible with each other, but not with those installed using method 4. This is due to the same signing key (ours) being using for 2 and 3, but a different signing key (F-Droid's) being used for 4. Building a debug APK using method 1 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!

+## Açıklama
+
+NewPipe herhangi bir Google çerçeve kütüphanesini, ya da YouTube API hizmetlerini kullanmaz. Gerekli web hizmetleri yalnızca gerekli bilgileri almak için kaynak olarak kullanılır, bu nedenle bu uygulama Google hizmetleri yüklü olmayan cihazlarda da kullanılabilir. Ayrıca, copyleft özgür yazılımı olan NewPipe'ı kullanmak için bir YouTube hesabına ihtiyacınız yoktur.

+
+## 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>
