 ## Usage
 
 ### Installing dependencies
 
 ```
-pipenv install --dev
+pip install -r requirements.txt
 ```
 
 ### Running development server
 
 ```
-pipenv run serve
+mkdocs serve  # or ./scripts/serve
 ```
 
 This will launch a server on http://localhost:8000. Content in the server will live-reload as changes are made. If large refactors of the site structure are made, it's advisable to stop the server, make the changes, then restart it.
 
 ### Production build
 
 ```
-pipenv run build
+mkdocs build  # or ./scripts/build
 ```
 
 This will build the site once, and place it in `site/` in the root of the project. This may be useful to see which files are rendered, and how exactly to access them.

 There are some rudimentary tests in the project. These are all run by the CI, and must pass before deployment.

+## Dependency management
+
+Add any new dependencies to `requirements.in`, then run `pip-compile`.
+
+To update existing dependencies, use `pip-compile --upgrade` for all or
+`pip-compile --upgrade-package <name>` for a specific one.
+
+If upgrading a dependency because this project's requirements have actually
+changed (i.e: we now depend on a feature in a particular version), then instead
+update the entry in `requirements.in` and run `pip-compile` as for a new
+dependency.
