Episode 2
After the PR exercise in episode 1, the instructor should show the PRs on GitHub, and select one to use as an example to request changes.
Episode 3
After the exercise in episode 2, the instructor should make an edit to the discussion page and push the change to simulate someone else’s PR having been merged.
Alternatively, a helper could submit a PR and the instructor could merge it so the learners have a genuine scenario to handle.
In order to re-use this lesson, the instructor should do a hard reset so that the discussion page is empty again.
