+### Docker

+To get started quickly, run the following command or build the Docker image:
+```bash
+docker run -p 8184:8184 -v /path/to/dimension/store:/data turt2live/matrix-dimension
+```
+
+In the `/path/to/dimension/store` make sure there is a file named `config.yaml`. This will be the configuration that Dimension uses.

+### Setting up Dimension
+
 If you didn't change the port, Dimension should now be running on port 8184. It's best to set up your environment so that Dimension runs on a dedicated subdomain that *is not* the same as your Riot domain. This is to help keep Riot and Dimension safe and secure. 
 
 In your Riot `config.json`, set the integration manager to be your Dimension URL. Replace `dimension.t2bot.io` in the example above (under "Configuring Riot to use Dimension") with your Dimension URLs.
