+## The GitHub CLI Client
+
+GitHub provides a [free CLI client](https://cli.github.com/) to simplify many aspects of interacting with GitHub repositories. Note that this utility is separate from `git`, and must be [installed separately](https://github.com/cli/cli#installation).
+
+This guide provides some examples of common operations, but be sure to check out the [GitHub CLI manual](https://cli.github.com/manual/) for a complete accounting of available commands.

 !!! danger "Don't Reset After Pushing"
     Resetting only works until you've pushed your local changes upstream. If you've already pushed upstream, use `git revert` instead. This will create a _new_ commit that reverts the erroneous one, but ensures that the git history remains intact.
+
+### Rebase from Upstream
+
+If a change has been pushed to the upstream branch since you most recently pulled it, attempting to push a new local commit will fail:
+
+```
+$ git push
+To https://github.com/netbox-community/netbox.git
+ ! [rejected]            develop -> develop (fetch first)
+error: failed to push some refs to 'https://github.com/netbox-community/netbox.git'
+hint: Updates were rejected because the remote contains work that you do
+hint: not have locally. This is usually caused by another repository pushing
+hint: to the same ref. You may want to first integrate the remote changes
+hint: (e.g., 'git pull ...') before pushing again.
+hint: See the 'Note about fast-forwards' in 'git push --help' for details.
+```
+
+To resolve this, first fetch the upstream branch to update your local copy, and then [rebase](https://git-scm.com/book/en/v2/Git-Branching-Rebasing) your local branch to include the new changes. Once the rebase has completed, you can push your local commits upstream.
