 Once you've set your secret you can create a new file in your workflow called crgpt.yml, which should look like something seen below. An important attribute to include, is the fetch-depth of the checkout action below. Currently the action only works when it has access to the repo's entire commit history.

+### Workflow yml option 2: Add a code review bot
+
+In this config, a GPT CR is triggered when a specific user is added as a "reviewer" in the Github UI. Create an additional Github account such as 'YourProject-ML-CR-bot', then specify the account username in the config.
+
+This option can save on API costs by only reviewing when explicity asked to. It can also be used to avoid reviewing PRs before they are ready (draft/WIP PRs).
+
+To trigger a re-review, simply remove and re-add the bot to the reviewers list.
