+Frontend (Springload)
+~~~~~~~~~~~~~~~~~~~~~
+
+The frontend uses webpack and npm.
+
+First, make sure you're using the correct node version:
+
+  nvm use
+
+If it tells you to install a new version, do so. Then run ``nvm use`` again.
+
+Install dependencies:
+
+  npm install
+
+Then to run the site in development mode locally:
+
+  npm start

 Setup pre-commit hooks

  * There are two options for types of components: async or sync.
  *
- *  - Async means it's a lazy-loaded component (loaded on demand).
- *    The import would look like,
- *
- *      import('./MyComponent/MyComponent');

  *    Sync components are included in the top-level JS bundle.
