+# Contributing
+
+First of all, thank you for considering a contribution to this project. 😊
+Whether it's a small fix, an idea, a bug report, or some feature code,
+actions that impact the project positively are always very welcome.
+
+## How to contribute
+
+Feel free to submit a PR directly, if your change is in code and small and isolated.
+If you're in doubt about whether your contribution is a good idea for the project,
+feel free to create an issue first discussing the change.
+This also applies for any larger changes; start with an issue instead of risking
+a large PR that doesn't get accepted, which would make everyone involved sad.
+
+## Terms
+
+By contributing code, you declare that you have the rights to add it,
+and you accept that it will be published in the project under the existing license.
