+#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](https://newpipe.slack.com/) is being used for project communication. Ask [me](https://github.com/theScrabi) to sign up.
+* Feel free to post suggestions, changes, ideas etc!

 ## Description
 
-NewPipe does not use any Google framework libraries, or the YouTube API. It only parses the website in order to gain the information it needs. Therefore this app can be used on devices without G-services installed. Also NewPipe does not store data on the YouTube website (no login), and it's free software.
