-Note: Editing this file doesn't update the mapping used by the `@msftbot` issue notification bot to tag owners. Some area owners prefer not to get those notifications.

+If you need to tag folks on an issue or PR, you will generally want to tag the owners (not the lead) for [area](#areas) to which the change or issue is closest to. For areas which are large and can be operating system or architecture specific it's better to tag owners of [OS](#operating-systems) or [Architecture](#architectures).
