 Much like the silent flight of an owl at night, these nodes are configured to
 minimize the system noise and let programs run undisturbed. The list of nodes is
 `owl[1-2]` and are available for jobs with SLURM.
+
+The contents of the nix store of the hut node is made available in the owl nodes
+when a job is running. This allows jobs to access the same paths that are on hut
+to load dependencies.
+
+For now, only the hut node can be used to build new derivations so that they
+appear in the compute nodes. This applies to the `nix build`, `nix develop` and
+`nix shell` commands.
