+Using a static build command
+------------
+
+If you want to use a build server such as webpack or vite.js to compile static assets in the background while you develop
+You can pass ``--static-build`` to enable the server to run a background subprocess to watch and build your static assets.
+You can define the subprocess command to run with the argument ``--static-build-command``, which defaults to ``npm run dev``
+
+Additionally, by default the output of the build command will merge with the servers output, but you can pass the option ``--static-build-quiet``
+to silence the output.
