OpenQ is unopinionated about how your work on your project! With one exception - how you close your GitHub Issues.
Add Closes ## to Your PR, and Done
Add Closes # with the issue number associated with the bounty.
This is how ya do it
This can be in the body or comment of your pull request.
Once merged, it may or may not close the issue automatically depending on whether or not the merge was targeted at the default branch. No matter - if Closes is present, and it's merged into your organization's repository, then that makes the bounty claimable by the PR author.
MAINTAINERS: Always watch for Closes comments on pull requests which you might have missed before!
Once you get the hang of it, you'll wonder why you ever manually closed issues to begin with 😉.
