+
+Learning HTMX by building a  the htmx contact.app
+
+## First time setup
+
+Create a virtual environment and activate it. Now from the root project directory run `./scripts/bootstrap`. This will install `pip-tools` and sync any dependencies for the first time.
+
+## Dependency management
+
+Dependencies are managed via [pip-tools].
+
+### Adding a dependency
+
+To add a dependency, edit `requirements.in` (or `dev-requirements.in`
+for dev dependencies) and add your dependency then run `pip-compile
+requirements.in`.
+
+### Syncing dependencies
+
+Run `pip-sync requirements.txt dev_requirements.txt`.
+
+## Testing
+
+Run the tests by invoking `py.test` in the project root.  Make sure you
+run any pending migrations beforehand.
