 The bad news is that the maintainers of the AI/ML packages may take considerable
 time to review and merge our changes. The good news is that we can begin testing
 without pointing to the main branch of the upstream repo.
-The parameter value of the `CLONE_URL` is very flexible.
-We literally just call `git clone $CLONE_URL`.
+We can use `REPO_ORG`, `REPO_NAME`, and an optional `REPO_BRANCH` to define which repo to clone.
 As such, we can point to an arbitrary branch on an arbitrary repo.
 While developing, we encourage developers to point to a feature branch
 on their own fork, and add a TODO with the JIRA ticket to update the url
