+== Getting an account ==
+
+You automatically have access to the machine if you are part of Dartmouth's Thayer School of Engineering.
+
+== ssh configuration ==
+
+Babylon is actually a cluster of 12 independent servers, so you need to first choose on which one you are going to log in. 
+The status of the cluster usage can be found here : https://cluster-usage.thayer.dartmouth.edu/.
+
+You can add the following lines to `~/.ssh/config` on your local machine:
+{{{
+#!sh
+Host babylon babylon?.thayer.dartmouth.edu
+   Hostname babylon?.thayer.dartmouth.edu
+   User USERNAME
+
+}}}
+and replace `USERNAME` by your Dartmouth NetID, which is your username.
+
+Once this is done, you can ssh discovery by simply doing:
+
+{{{
+#!sh
+ssh babylonX 
+}}}
+
+with X the number of the machine you want to access
+
+== Password-less ssh ==
+
+This machine does not support public key authentification
+
+== Environment ==
+
+On babylon, add the following lines to `~/.bashrc`:
+{{{
+#!sh
+export ISSM_DIR=PATHTOTRUNK
+source $ISSM_DIR/etc/environment.sh
+alias ma='matlab -nodesktop -nosplash -r "addpath $ISSM_DIR/src/m/dev; devpath;"'
+}}}
+
+''Log out and log back in'' to apply this change.
+
+== Installing ISSM on babylon ==
+
+Babylon has both Intel and GNU compilers. Installation should be done with the Intel compilers. You can follow the instructions on the website [http://issm.jpl.nasa.gov/download/unix/]. Choose Petsc v3.15 or later. You should not need Python.
+
+Use the following configuration script (adapt to your needs):
+
+{{{
+#!/bin/bash
+./configure \
+   CC=icc CXX=icpc F90=ifort FC=ifort \
+   --prefix=${ISSM_DIR} \
