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

 * 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.

 ## 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.
+ 2. Download the APK from [GitHub Releases](https://github.com/TeamNewPipe/NewPipe/releases), [compare the signing key](#apk-info) 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, and 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.
  5. If you're interested in a specific feature or bugfix provided in a Pull Request in this repo, you can also download its APK from within the PR. Read the PR description for instructions. The great thing about PR-specific APKs is that they're installed side-by-side the official app, so you don't have to worry about losing your data or messing anything up.
@@ -100,12 +104,20 @@ You can install NewPipe using one of the following methods:
 We recommend method 1 for most users. APKs installed using method 1 or 2 are compatible with each other (meaning that if you installed NewPipe using either method 1 or 2, you can also update NewPipe using the 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. When using method 5, each APK is signed with a different random key supplied by GitHub Actions, so you cannot even update it. You will have to backup and restore the app data each time you wish to use a new APK.
 
 In the meanwhile, if you want to switch sources for some reason (e.g. NewPipe's core functionality breaks and F-Droid doesn't have the latest 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
+1. Back up your data via Settings > Backup and Restore > Export Database so you keep your history, subscriptions, and playlists
 2. Uninstall NewPipe

+4. Import the data from step 1 via Settings > Backup and Restore > Import Database
 
-<b>Note: when you're importing a database into the official app, always make sure that it is the one you exported _from_ the official app. If you import a database exported from an APK other than the official app, it may break things. Such an action is unsupported, and you should only do so when you're absolutely certain you know what you're doing.</b>
