GitHub supports many extras in Markdown that help you reference and link to people. If you ever want to direct a comment at someone, you can prefix their name with an @ symbol: Hey @kneath — love your sweater!
But I have to admit, tasks lists are my favorite:
- This is a complete item
- This is an incomplete item
When you include a task list in the first comment of an Issue, you will see a helpful progress bar in your list of issues. It works in Pull Requests, too!
And, of course emoji!
This is a third-tier heading
You can use one # all the way up to ###### six for different heading sizes.
