 Pull request labeler triages PRs based on the paths that are modified in the PR.
 
+Note that only pull requests being opened from the same repository can be labeled.  This action will not currently work for pull requests from forks -- like is common in open source projects -- because the token for forked pull request workflows does not have write permissions.
+
 ## Usage
 
 ### Create `.github/labeler.yml`
diff --git a/action.yml b/action.yml
