 ## Running CI on HPC from pull requests
 
+> :warning: **Note:** The GitLab mirror integration is currently disabled due to technical issues. This section describes functionality that is temporarily unavailable.

 For security and accounting reasons, a few extra steps are needed in order to run the contents of a pull request on HPC:
