 This GitHub Action sets up CernVM-FS for use in GitHub Workflows.

 ```
 By default 	`*.cern.ch, *.egi.eu, *.opensciencegrid.org *.hsf.org` repositories are available.
 
-The Action also works with runners of type `macos-10.15`, however in this case it is necessary to specify which repositories you want to mount (via the variable `cvmfs_repositories`), as there is not auto mount for macOS. A minimal example of usage on `macos-10.15` is:
-```yaml
-jobs:
-  macOS-minimal:
-    runs-on: macos-10.15
-    steps:
-    - uses: cvmfs-contrib/github-action-cvmfs@v2

-    - name: Test CernVM-FS
-      run: ls /Users/Shared/cvmfs/sft.cern.ch/
-```
-Beware that because the runner cannot be rebooted in the macOS case, the repositories are mounted under `/Users/Shared/cvmfs/`

 ## Limitations
 
-This GitHub Action is only expected to work in workflows that [run on](https://docs.github.com/en/free-pro-team@latest/actions/reference/workflow-syntax-for-github-actions#jobsjob_idruns-on) ubuntu and macOS targets (and even then likely only `ubuntu-latest`). This exludes the `windows` targets.
