+The software can take a few seconds to start up, mostly because it is downloading updated files containing the various
+bits of reference data it uses. This is normal, don't panic! Once you see `You can access your copy of Spothole at
+http://localhost:8080` in the log, your server is good to go.
 
 If you see some errors on startup, check your configuration, e.g. in case you have specified a port for the web server
 that is already in use by something else.
 
+### Running using Docker
+
+Spothole comes with a Docker configuration to make it easy to run it in a containerised environment. To set it up using
+Docker, the easiest way is to use a Docker Compose file. Create a new directory such as `/opt/docker/spothole` and
+create a `compose.yaml` file inside it with the following contents:
+
+```yaml
+services:
+  spothole:
+    container_name: spothole
+    build:
+      context: https://git.ianrenton.com/ian/spothole.git#main
+    restart: unless-stopped
+    ports:
+      - "8080:8080"
+    volumes:
+      - ./config.yml:/app/config.yml
+      - ./cache:/app/cache
+```
+
+Save the file. You will still need to create a copy of `config-example.yml` and name it `config.yml`, though with the
+Docker setup nothing has actually been downloaded yet, so you will have to copy the example from the repository some
+other way, e.g. [from the repo in a web browser](https://git.ianrenton.com/ian/spothole/src/branch/main/config-example.yml).
+
+With that in place, run `docker compose up` and you should be good to go. To detach, press `d` or run the command with
+the `-d` flag.
