+# :wave: How can I contribute?
+
+First off, thank you for helping to improve this chart! :heart_eyes: :pray:
+
+## Testing
+
+To test the chart locally, before submitting changes, run `./ci/scripts/local-ci.sh`
+
+## Submitting changes
+
+Please send a [GitHub Pull Request](https://github.com/funkypenguin/helm-docker-mailserver/pull/new/master) with a clear list of what you've done (read more about [pull requests](http://help.github.com/pull-requests/)).
+
+When you send a pull request, please make sure all of your commits are atomic (one feature per commit), and bump the chart version in `chart.yaml`
+
+Always write a clear log message for your commits. One-line messages are fine for small changes, but bigger changes should look like this:
+
+    $ git commit -m "A brief summary of the commit
+    > 
+    > A paragraph describing what changed and its impact."
+
+Thanks again!
