+Development
+===========
+
+For the best development experience:
+
+1. Install django-prose-editor in editable mode in your project:
+
+   .. code-block:: shell
+
+       pip install -e /path/to/django-prose-editor
+
+2. Run ``yarn && yarn dev`` in the django-prose-editor directory to watch for
+   asset changes.
+
+When using ``yarn dev``:
+
+- The generated CSS and JavaScript is not minified, making it easier to debug.
+- Source maps are generated to help identify exactly where in the source code
+  an error occurs.
+- The watcher will rebuild files automatically when you make changes.
+
+Source maps are generated in development mode (``yarn dev``) for easier
+debugging, but not included in production builds to keep the package size
+manageable. The JavaScript in this project is quite extensive, so source maps
+would significantly increase the distribution size.
+
+The pre-commit configuration includes a hook that prevents committing files
+with source map references, ensuring that development artifacts don't make it
+into the repository.
+
+Code Style and Linting
+---------------------
+
+This project uses pre-commit hooks to enforce coding style guidelines. We use
+Ruff for Python linting and formatting, Biome for JavaScript/TypeScript linting
+and formatting and a few other hooks.
+
+To set up pre-commit using uv:
+
+.. code-block:: shell
+
+    uv tool install pre-commit
+    pre-commit install
+
+Pre-commit will automatically check your code for style issues when you commit
+changes.
