+The following rules are in place, please respect them.
+
+# Rules
+
+Due to the cluster [structure](cluster/cluster-structure):
+
+- Job **must** be sent to calculus nodes
+- Job thus **can never** be done on the master (where the user arrives with a ssh connection)
+- The nodes must be choosen wisely as some of them have a time limits (all_5hrs, and all_24hrs)
+- Job **must be sent** using  [slurm](cluster/slurm/slurm-home)
+
+If the rules above are not respected and that a problem is detected on the cluster, the SEGI can and will kill your job. 
+
+If any problems is encountered with the utilisation of slurm, the bioinformatic team will gladly help you (contact: bioinfo.giga@uliege.be)
