 ## CompatHelper
 
 The CompatHelper workflow is designed to periodically check dependencies for breaking
-releases, and if so make PRs to bump the compat versions. The workflow would look like:
-Note this workflow checks both the Julia [General registry](https://github.com/JuliaRegistries/General)
