 In this file, we configure options for the SLURM submission on the test cluster.
 A example config can be found in `example.gitlab-ci.yml`.
 
+Each job needs to have the tag `testcluster`.

 SLURM options can be set either globally in the `variables` section, or on a per-job basis.
 The latter will override global variables with the same name.

+This configuration already suffices to have the CI jobs running on the node `phinally`, with `benchmark-broadep2` being executed on `broadep2`.
 With "phinally" being the default node and time limit by default at 120, even having no configuration at all would work just fine.
 
 To pick a node to run your job on, set `SLURM_NODELIST` to the nodes hostname.
