+Use case: rsh
+^^^^^^^^^^^^^^
+
+If your cluster uses a rsh variant like ``mrsh`` or ``krsh``, you may want to
+change it in the library defaults.
+
+An example file is usually available in
+``/usr/share/doc/clustershell-*/examples/defaults.conf-rsh`` and could be
+copied to ``/etc/clustershell/defaults.conf`` or to an alternate path
+described above. Basically, the change consists in defining an alternate
+distant worker by Python module name as follow::
+
+    [task.default]
+    distant_workername: Rsh
+
+
+.. _defaults-config-slurm:
+
+Use case: Slurm
+^^^^^^^^^^^^^^^
+
+If your cluster naming scheme has multiple dimensions, as in ``node-93-02``, we
+recommend that you disengage some nD folding when using Slurm, which is
+currently unable to detect some multidimensional node indexes when not
+explicitly enclosed with square brackets.
+
+To do so, define ``fold_axis`` to -1 in the :ref:`defaults-config` so that nD
+folding is only computed on the last axis (seems to work best with Slurm)::
+
+    [nodeset]
+    fold_axis: -1
+
+That way, node sets computed by ClusterShell tools can be passed to Slurm
+without error.

+
+* in some cases, :ref:`timers <configuring-a-timer>` were too fast due to an
