-## How to test
-
-* Run `npm run test`
+* Installing
+  + Run `npm install`
+  + You can now start the app in a container by running `npm run start:containers` (and shut it down with `npm run stop:containers`).
+* Running
+  + 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.
+  + The docker image launches the nodejs app with nodemon, so changes to the code will be available immediately.
