-How to use these scripts
-------------------------
+The objectives of the scripts
+-----------------------------
+These scripts will 
+1) download the needed, 
+2) extract the region needed for NEMO-Nordic,
+3) convert the units as needed for NEMO-Nordic,
+4) save the final files as netCDF.
 
-To be written...
 
+Instructions
+------------
+Basically, users have only to adopt the "Configure section" in the
+main script - Create_NEMO_forcing_from_UERRA.py
+1) Set the dates your are interested in.
+2) Define directories for downloaded data, the final data, and
+   a directory for temporary files.
 
+Then, all you have to do is to run the main script...
+Create_NEMO_forcing_from_UERRA.py
+
+The scripts need some time to run. Especially the downloading of data
+from the MARS archive takes time...
+
+
+Technical details
+-----------------
+The scripts were developed and tested on HPC-system in Linköping/Sweden,
+namely the cluster called "Bi".
+Here, we used Python 2.7.9.
+We involve also CDO commands to a large degree. These need to be compiled
+into your python version.
+Moreover, to fetch data from the MARS archive, you will need the
+corresponding modules. Please find out on ECMWF's websides.
+Otherwise, used modules should be standard.
