+# Contribution Guideline
+
+First of all: I am thankful for any contribution this project gets.
+
+## Creating Issues
+
+You found a bug, you miss some feature in the project or have an idea how to
+improve the code? Then [create a GitHub issue](https://github.com/progsource/maddy/issues/new).
+
+## Creating Pull-Requests
+
+* Use a branch other than master.
+* Add yourself to the `AUTHORS` file.
+* Try to stick with the code style the files are having right now.
+* Write in your commit messages what/why you did something. Often times a one-liner might be enough, but if you want to write more, make an empty line in between like:
+  ```
+  Short description
+
+  More and longer text for the commit message with some more information.
+  That can go over multiple lines.
+  ```
+  Do not include Github issue ticket numbers inside commit messages.
+* Explain for what your PR is for - like providing a use-case or something similar.
+* Update documentation of the Markdown syntax if anything changed there. (`docs/definitions.md`)
+* Add a changelog entry at "Upcoming" inside of `CHANGELOG.md`
+* Make sure, that the tests are successful.
