 - Report bugs
 - If you want to contribute a pull request, please add https://gist.github.com/siegfriedpammer/75700ea61609eb22714d21885e4eb084 to your `.git/hooks` to prevent checking in code with wrong indentation. We use tabs and not spaces. The build server runs the same script, so any pull requests using wrong indentation will fail.
