 ## Commands
 
 - `docker build -t router .` builds the router image with the tag `router` for local testing.
+  - You can use the `--build-arg APOLLO_ROUTER_VERSION=v1.55.0` to set the version of the Apollo Router docker image you want to use.
 - `rover dev --supergraph-config supergraph.yaml --router-config router.yaml` to run the Router locally without Docker (using [Rover]). You'll need to update the `supergraph.yaml` file to point at the local versions of your subgraphs. **Make sure to set the required environment variables ahead of time!**
 - `docker run -it --env APOLLO_KEY --env APOLLO_GRAPH_REF -p4000:4000 router` runs the same router image you'll run in production. You can now query the router at `http://localhost:4000`.
     - Make sure to set the env vars `APOLLO_KEY` and `APOLLO_GRAPH_REF` first
