+and the addition of the `--helm-config-access-token-variable` parameter.
+
+The `--helm-config-access-token-variable` parameter configures how an
+`access.yaml` file is written to the HLD for `fabrikate` to consume when
+rendering helm charts. For more information on authenticating with private git
+repositories when rendering helm charts, please refer to
+[fabrikate's documentation](https://github.com/microsoft/fabrikate/blob/master/docs/auth.md).
+
+When the bedrock.yaml is committed, all the pipelines created, and the HLD
+repository is populated, you must add the environment variable,
+`FABRIKAM_HELM_CHARTS_REPO_PAT` to the HLD to Materialized pipeline as a
+pipeline variable. To do so, find the HLD to Materialized pipeline in the
+pipelines view on Azure DevOps, select it, select `Variables`, then select
