+==== Setup ====
+
+Firstly `init_nemovar.sh` is run. 
+Links are created to the ancillary files, the coordinates and the bathymetry. 
+Additionally the `$DIR_INPUT` directory is created and the innovations, the assimilation background and the altimeter bias are linked into it. 
+
+The namelist used is called `namelist.nemovar`. It is updated with the variable:
+{{{
+nn_date0 "$(rose date -c -f %Y%m%d)"
+}}}
+
+The script then calls `run_nemovar.sh`. 
+
+
+
+==== Run ====
+
+
+==== Finalisation ====
+
+If `run_nemovar.sh` completes succesfully then more steps in `init_nemovar.sh` are performed. 
+The directory `$OUTDIR_INCREMENTS` is created and the increments produced in the NEMOVAR stage are combined into one file:
+{{{
+rebuild_nemo increments_o01 ${NEMO_NPROC}
+mv increments_o01.nc ${OUTDIR_INCREMENTS}/assim_background_increments.nc
+}}}
+The same is also done for the altimeter bias (`altbias`). 
+
+The file `assim_background_increments.nc` is one of the more important files; it contains the increments after each stage. 
+These increments are applied to the background to create the analysis **x,,a,,**.
