# Pull Requests Tagging

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).

## Areas

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. To update those notifications, contact any one of `@danmoseley`, `@jeffschw`, `@marek-safar`, `@ericstj`, `@karelz`, or `@jeffhandley`; they have permissions to update [`msftbot` configuration](https://portal.fabricbot.ms/bot/?repo=dotnet/runtime). If you're a community member interested in these notifications, you won't appear in this table but we can add you to notifications - just let us know.
