-For Docker:
+You can run it with Docker:
 
 ```bash
-$ docker run -p 6379:6379 --name redis6 -d redis:6 
+$ docker-compose up -d

-Ensure you have SQLite3 installed.
+You can also run redis-cli in the container
+```bash
+$  docker exec -it redis-caching-slow-database-queries redis-cli

+> NOTE: If you're using Redis Enterprise Cloud, you'll need the hostname, port number, and password for your database.  Use these to set the `REDIS_OM_URL` environment variable like this:
+
+```bash
+$ export REDIS_OM_URL=redis://default:<password>@<host>:<port>
+```
+
+(**This step is not required when working with Docker as the Docker container** runs Redis on `localhost` port `6379` with no password, which is the default connection that Redis OM uses.)
+
+For example if your Redis Enterprise Cloud database is at port `9139` on host `enterprise.redis.com` and your password is `5uper53cret` then you'd set `REDIS_OM_URL` as follows:
