+# Basics
+### Linux Tutorial
+You can find an introduction to UNIX/Linux systems here: https://www.tutorialspoint.com/unix/index.htm 
+
+And the most useful commands on the [Basic Linux Commands Wiki Page](/computing/linuxbasics).
+
+### How to write shell scripts
+***[Shell Scripts](/computing/shell_scripts)***: These are useful for automation of simple commands from the command line.
+
+# The LHCb Heidelberg Computing cluster
+### D0 Cluster
+***[D0 Cluster](/computing/cluster)***: a server cluster dedicated to local LHCb computing
+### Job Submission
+***[qsub](/computing/qsub)*** : submitting many jobs to the cluster
+
+### NAF
+***[NAF](http://naf.desy.de)*** Please note that NAF is not DESY T2. So there is no possibility to use LHCb frameworks (DIRAC, Ganga) to schedule jobs there, nor a possibility to up/down-load LHCb data automatically (LHCb computing policy is explicitly against any national resources, so that is not just technical limitation).

+
+All new LHCb students are encouraged to attend the Starter-kits when offered: https://lhcb.github.io/starterkit-lessons/first-analysis-steps/README.html
