+
+Apex serves as the login node to the rest of machines in jungle. Connect to it
+by accessing `ssflogin.bsc.es`, only from the apex you will be able to see other
+machines.
+
+Use `sinfo` to see which nodes are available and `salloc` to request them (see
+the manual for more details). Avoid doing large builds or computations in apex,
+use a different node instead.
+
+The home is mounted from a hardware RAID 5 of 4 disks, and is shared across
+other machines.
