 In this example, we have to mount the local definition of the supergraph into our image, _and_ specify the location of the file. It doesn't have to be mounted in the `/dist/schema` directory, but it's a reasonable location to use. We must specify the configuration file location as well, since overriding the default params will override our default config file location. In this case, since we don't want to change our router configuration but want to make sure it's used, we just specify the default location of the default configuration.
 
+### Using an OCI image reference

+You can use the `--graph-artifact-reference` option to fetch the supergraph schema from an OCI image:

+```bash
+docker run -p 4000:4000 \
+  --env APOLLO_KEY="<your-graph-api-key>" \
+  --env GRAPH_ARTIFACT_REFERENCE="<your-oci-reference>" \

+```
+
+When using this option, the router will fetch the schema from the specified OCI image instead of using Apollo Uplink.

+## Specifying the supergraph
+
+If you don't want to automatically update your supergraph via [Apollo Uplink](/federation/managed-federation/uplink/), or you don't have connectivity to access Apollo Uplink from your environment, you have two options:
+
+1. Using a local supergraph file, as documented in the [Configuring using local files](#configuring-using-local-files) section.
+1. Using an [OCI image reference](#using-an-oci-image-reference)
+
+### Using an OCI image reference
+
+You can use the `GRAPH_ARTIFACT_REFERENCE` environment variable to fetch the supergraph schema from an OCI image:
+
+```bash
+docker run -p 4000:4000 \
+  --env APOLLO_KEY="<your-graph-api-key>" \
+  --env GRAPH_ARTIFACT_REFERENCE="<your-oci-reference>" \

+  ghcr.io/apollographql/apollo-runtime:<runtime-image-version>
+```
+
+When using this option, the router will fetch the schema from the specified OCI image instead of using Apollo Uplink. Additional information on graph artifacts is available in the [router CLI options documentation](/docs/graphos/routing/configuration/cli#command-line-options).

 ## Running a specific Router and MCP version
 
 The container has a tagging scheme that consists of three parts, the container version, the Apollo Router version, and the MCP Server version, each separated by underscores.
