The lesson
Put a one-line example of the feature working in most changelog sections, so the reader pictures their own use before reading the setup.
A video at the top shows a prompt typed into a box: "@Linear create a loop that runs whenever a PR is merged". Sections like Slack and GitHub triggers and Custom loop templates each state what they do, then give a case, such as drafting a QA plan when a PR gets a "ready for testing" label.
Don't copy the Loops product vocabulary or assume readers know it. Keep the pairing of a short capability statement with one named, everyday example.
