+This folder has Github Actions for this repo. 
+
+** pr-labler **
+
+This is responsible for tagging our prs automattically. The primary thing it does is tags internal vs external (to the team) PRs. It will
+also tag PRs with `area/*` tags based upon the files being changes in the PR. This is run on `pull_request_target` which only runs what is 
+in the repo not what is in the Pull Request. This is done to help guard against a PR running and changing. For this, the Action should NEVER 
+download or checkout the PR. It is purely for tagging/labeling not CI.
