+#Contribution
+
+This document contains guidelines on making contributions to NewPipe.
+
+## Programming
+
+* Follow the [Google Style Guidelines](https://google.github.io/styleguide/javaguide.html)
+* Make a new feature on a separate branch, not on the master branch
+* Make a [pull request](https://github.com/theScrabi/NewPipe/pulls) if you're done with your changes
+* When submitting changes, you agree that your code will be GPLv3 licensed
+
+## Commit messages
+
+* The subject line of your commit message shouldn't be longer than 72 characters
+* Try to keep each line of your commit message 72 characters to ensure proper
+ compatibility with all git tools
+* [This guide](http://chris.beams.io/posts/git-commit/) goes more in depth on what makes a good commit message
+
+## Translation
+
+* NewPipe can be translated on [weblate](https://hosted.weblate.org/projects/newpipe/strings/)
+
+## Issue reporting
+
+* Search the [existing issues](https://github.com/theScrabi/NewPipe/issues) first to make sure your issue hasn't been reported before
+* Check if this issue is already fixed in the repository
+* When making bug reports, be sure to tell which version of NewPipe you are using and the steps to reproduce the problem
+* Please include a log if you can
+
+## Communication
+
+* For the time being, [Slack](http://invite.chschtsch.ml/) is being used for project communication
+* Feel free to post suggestions, changes, ideas etc!
