 ### Prerequisites
-This action depends on the user to call the companion action `uses: cvmfs-contrib/github-action-cvmfs@v2` before using `uses: eic/run-cvmfs-osg-eic-shell@v1`, which will install CVMFS on the node. GitHub Actions currently do not support calling the action `github-action-cvmfs` from within `run-cvmfs-osg-eic-shell`, this needs to be done explicitly by the user.
