 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.

 ## 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!

+* 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.

 ## 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/
+ 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.net/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.
 
-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.
