+# Contribution guidelines
+
+Contributing to this project should be as easy and transparent as possible, whether it's:
+
+- Reporting a bug
+- Discussing the current state of the code
+- Submitting a fix
+- Proposing new features
+
+## Github is used for everything
+
+Github is used to host code, to track issues and feature requests, as well as accept pull requests.
+
+Pull requests are the best way to propose changes to the codebase.
+
+1. Fork the repo and create your branch from `main`.
+2. If you've changed something, update the documentation.
+3. Make sure your code lints (using `scripts/lint`).
+4. Test you contribution.
+5. Issue that pull request!
+
+## Any contributions you make will be under the MIT Software License
+
+In short, when you submit code changes, your submissions are understood to be under the same [MIT License](http://choosealicense.com/licenses/mit/) that covers the project. Feel free to contact the maintainers if that's a concern.
+
+## Report bugs using Github's [issues](../../issues)
+
+GitHub issues are used to track public bugs.
+Report a bug by [opening a new issue](../../issues/new/choose); it's that easy!
+
+## Write bug reports with detail, background, and sample code
+
+**Great Bug Reports** tend to have:
+
+- A quick summary and/or background
+- Steps to reproduce
+  - Be specific!
+  - Give sample code if you can.
+- What you expected would happen
+- What actually happens
+- Notes (possibly including why you think this might be happening, or stuff you tried that didn't work)
+
+People *love* thorough bug reports. I'm not even kidding.
+
+## Use a Consistent Coding Style
+
+Use [black](https://github.com/ambv/black) to make sure the code follows the style.
+
+## Test your code modification
+
+It comes with development environment in a container, easy to launch
+if you use Visual Studio Code. With this container you will have a stand alone
+Home Assistant instance running and already configured with the included
+[`configuration.yaml`](./config/configuration.yaml)
+file.
