 * Installing
   + Run `npm install`
   + You can now start the app in a container by running `npm run start:container` (and shut it down with `npm run stop:container`).
+* Building
+  + The front-end code gets built with webpack. You can build it anytime with `npm run build`.
+  + For development, it's useful to build continuously. You can run `npm run watch` and webpack will build every time you edit a monitored file.
 * Running
   + Copy the `.env.dist` file into `.env` and set any values you like.
   + The app will run in a single container, with a Postgres database, a caddy webserver and the nodejs app.
   + Note that the container doesn't come with a volume for Postgres: default behaviour is to start from scratch every time you create the container, delete everything every time you delete the container.
+  + You probably want to run migrations to get the database into proper state. You can do so with `npx sequelize-cli db:migrate`.
   + The docker image launches the nodejs app with nodemon, so changes to the code will be available immediately.
+  + Furthermore, since the git repository gets mounted live into the docker container, the live changes made by webpack watch mode will also be available as you work on front end files.
   + The Postgres database is reachable from the host, so you can use your favourite SQL client to access it.
   + You can format with `npm run format` and lint with `npm run lint`.
