+====== Newbies guide to running NorESM ======
+The purpose of this page is to be able to set up and run the model within 15 minutes. For more advanced configuration, please consult http://www.cesm.ucar.edu/models/ccsm4.0/ccsm_doc/ug.pdf
+This guide assumes that you have properly checked out the model to some directory which will call $NORESM. This directory will contain subdirectories "models" and "scripts".
+=== Go to scripts directory ===
+cd $NORESM/scripts
+=== Create the case ===
+./create_newcase  -case ../cases///casename/// -mach //machinename// -res f19_g16 -compset //compsetname//
+(where //casename//, //machinename// and //compsetname// are user input. Res is imodel resolution. The user can //not// give any resolution since input data are not prepared for any resolution in NorESM.)
+To see a list of available composets type
+./create_newcase -list
+The simplest case which runs production tagged aerosols and data ocean in a VERY coarse resolution is
+./create_newcase -case /path/to/where/I/store/the/case -compset NFPTAERO -mach hexagon -res f10_f10
+=== Configure the case ===
+cd $NORESM/cases///casename//
+edit any configuration files (understand env_conf.xml and env_run.xml)
+./configure -case (in NorESM1 / CAM4)
+or
+./cesm_setup (in NorESM2 / CAM5)
+After these two commands, the case is configured
+=== Build the case ===
+.///casename//.//machinename//.build (NorESM1 / CAM4)
+.///casename//.build (NorESM2 / CAM5)
+=== Run the case ===
+qsub //casename//.//machinename//.run
+=== Example ====
+There are already several pre-defined compsets. They all have long and short names. As and example we can use the compset N_2000_AEROSLO_CN (with short name N2000AERCN). Thus a valid command on the machine //hexagon// is:
+./create_newcase  -case /path/to/my/case/directory/ -mach hexagon -res f19_g16 -compset N2000AERCN
+(will run a "year 2000" CAM4/NorESM1 case with the Oslo-aerosols)
+./create_newcase  -case /path/to/my/case/directory/ -mach hexagon -res f19_g16 -compset FAMIPC5
+(will configure the "default" atmoshere-only simulation of CAM5)
+===Important files===
+The most important files to understand in your case-directory are:
+  * env_run.xml (model run type, how long time to run etc)
+  * env_conf.xml (model configuration)
