+# Setting up the cluster:
+This is a short summary of the steps to be followed to access the experimental data and the compute resources available for Cristallina users.
+
+###  Set up the enviroments paths
+Once on ra (ssh user_name@ra.psi.ch as described above), create a symbolic link to the bash file:
+`ln -s /sf/cristallina/bin/setting_up_ra.sh ~`
+
+and run it
+`sh setting_up_ra.sh`
+
+This should set up the working python enviroments. For the analysis, please use the 'analysis' enviroment, which is set as a default one. 
+
+### Running own jupyter instance
+Once on ra, copy the bash file:
+`cp /sf/cristallina/bin/jupyter_on_ra.sh ~`
+and run it.
