+### Docker & docker compose
+
+You can build a production image by running `docker build .` in the repo's root.
+
+For development, there's a `docker-compose.yml` that mounts the app code (for hot reload of code changes) and default config. Before running it, you need to install the dependencies:
+
+```
+$ docker compose run --rm web npm install --no-optionals
+$ docker compose up
+```
