+Welcome to the jungle, a set of machines with no imposed rules that are fully
+controlled and maintained by their users.
+
+The configuration of all the machines is written in a centralized [git
+repository][config] using the Nix language for NixOS. Changes in the
+configuration of the machines are introduced by merge requests and pass a review
+step before being deployed.
+
+[config]: https://pm.bsc.es/gitlab/rarias/jungle
+
+The machines have access to the large list of packages available in
+[Nixpkgs][nixpkgs] and a custom set of packages named [bscpkgs][bscpkgs],
+specifically tailored to our needs for HPC machines. Users can install their own
+packages and made them system-wide available by opening a merge request.
+
+[nixpkgs]: https://github.com/NixOS/nixpkgs
+[bscpkgs]: https://pm.bsc.es/gitlab/rarias/bscpkgs
+
+We have put a lot of effort to guarantee very good reproducibility properties in
+the configuration of the machines and the software they use.

+From the hut we monitor and control other nodes. It consist of one node only,
+which is available at `hut` or `xeon07`. It runs the following services:
+
+- Prometheus: to store the monitoring data.
+- Grafana: to plot the data in the web browser.
+- Slurmctld: to manage the SLURM nodes.
+- Gitlab runner: to run CI jobs from Gitlab.
+
+This node is prone to interruptions from all the services it runs, so it is not
+a good candidate for low noise executions.

+`owl[1-2]` and are available for jobs with SLURM.
