  Encountering outdated documentation is not a rare occurrence for developers
and users in the software engineering community. To ensure that software
documentation is up-to-date, developers often have to manually check whether
the documentation needs to be updated whenever changes are made to the source
code. In our previous work, we proposed an approach to automatically detect
outdated code element references in software repositories and found that more
than a quarter of the 1000 most popular projects on GitHub contained at least
one outdated reference. In this paper, we present a GitHub Actions tool that
builds on our previous work's approach that GitHub developers can configure to
automatically scan for outdated code element references in their GitHub
project's documentation whenever a pull request is submitted.
