+
+## Issue reporting/feature request
+
+* Search the [existing issues](https://github.com/theScrabi/NewPipe/issues) first to make sure your issue/feature hasn't been reported/requested before
+* Check if this issue/feature is already fixed/implemented in the repository
+* If you are an android/java developer you are always welcome to fix/implement an issue/a feature yourself
+* Use english
+
+## Bugfixing
+* If you want to help NewPipe getting bug free, you can send me a mail to tnp@newpipe.schabi.org to let me know that you intent to help, and than register at our [sentry](https://support.schabi.org) setup. 
+
+## Translation
+
+* NewPipe can be translated on [weblate](https://hosted.weblate.org/projects/newpipe/strings/)
+
+## Code contribution
+
+* Stick to NewPipe style guidelines (just look the other code and than do it the same way :) )
+* Do not bring nonfree software/binary blobs into the project (keep it google free)
+* Stick to [f-droid contribution guidelines](https://f-droid.org/wiki/page/Inclusion_Policy)
+* Make changes on a separate branch, not on the master branch (Feature-branching)
+* When submitting changes, you agree that your code will be licensed under GPLv3
+* Please test (compile and run) your code before you submit changes!!!
+* Try to figure out you selves why CI fails, or why a merge request collides
+* Please maintain your code after you contributed it.
+* Respond yourselves if someone request changes or notifies issues
+
+## Communication
+

-NewPipe is a lightweight youtube frontend for android. It's supposed to be used without the youtube-api and without any google play services. NewPipe only parses the youtube website in order to gain the information it needs.

-This a very early version of the app, so not all functionality is implemented, and there may still be a lot of bugs. But all in all it's doing what it is supposed to do. It makes it possible to watch youtube videos. So don't be cruel to this app. It will improve...
