+
+## Development
+
+### Setup environment
+
+We use [Hatch](https://hatch.pypa.io/latest/install/) to manage the development environment and production build. Ensure it's installed on your system.
+
+### Run unit tests
+
+You can run all the tests with:
+
+```bash
+hatch run test
+```
+
+### Format the code
+
+Execute the following command to apply linting and check typing:
+
+```bash
+hatch run lint
+```
+
+### Publish a new version
+
+You can bump the version, create a commit and associated tag with one command:
+
+```bash
+hatch version patch
+```
+
+```bash
+hatch version minor
+```
+
+```bash
+hatch version major
+```
+
+Your default Git text editor will open so you can add information about the release.
+
+When you push the tag on GitHub, the workflow will automatically publish it on PyPi and a GitHub release will be created as draft.
+
+## Serve the documentation
+
+You can serve the Mkdocs documentation with:
+
+```bash
+hatch run docs-serve
+```
+
+It'll automatically watch for changes in your code.
