 Get the NEMO Schwarz sources from the repository:
 {{{
-svn co svn+ssh://forge/ipsl/forge/projets/cocoa/svn/
+svn co svn+ssh://forge/ipsl/forge/projets/cocoa/svn/SCHWARZ_IPSLCM6VLRNOP/SOURCES/NEMO MY_NEMO
 }}}
+
+All the needed files to modify NEMO for the Schwarz algorithm are in this directory: `MY_NEMO`.
+
+The rest of the work consist in checking the subroutines in `MY_NEMO` vs those in `SOURCES/NEMO`, `NEMOGCM/CONFIG/ORCA2_LIM3_PISCES/MY_SRC` or `NEMOGCM/NEMO/OPA_SRC`.
+
+Review each `.f90` in `MY_NEMO`: 
+1. If it is present in `SOURCES/NEMO` do a vimdiff between the two and make the needed changes to the file in `SOURCES/NEMO` to include Schwarz modifications.
+2. If it is present in `NEMOGCM/CONFIG/ORCA2_LIM3_PISCES/MY_SRC` but not in `SOURCES/NEMO` copy the file to `SOURCES/NEMO` do a vimdiff with the `MY_NEMO` file and include Schwarz modifications.
+3. If it is neither in `ORCA2_LIM3_PISCES/MY_SRC` nor in `SOURCES/NEMO` copy the file from `NEMOGCM/NEMO/OPA_SRC` review the changes in `MY_NEMO` with vimdiff and include them in the `SOURCES/NEMO` file.
+
+When you have an updated version of every `.f90` files from `MY_NEMO` in `SOURCES/NEMO` you can recompile NEMO.
+
+You will still have to modify the NEMO namelist: `namelist_ORCA2_cfg`.
+
+In your submission directory (where you have `config.card` and `Job_MYEXPERIMENT` files), go to `PARAM` and modify `namelist_ORCA2_cfg`.
+
+Add `mswr`, `ksout`, `kall` and `cplfrq` to the `&namrun` section:
+{{{
+   mswr        =  010   !  number of scwharz iterations
+   ksout       =  010   !  Schwarz iteration for output
+   kall        =  001   !  first iteration with all physics
+   ncplfrq     =  86400 !  coupling frequency in seconds
+}}}
+
+You should try to run a simulation with `mswr=1` `ksout=1`, `kall=1` and `ncplfrq=` the coupling frequency of your reference simulation as a test.
+
+It should give you the same result as without Schwarz.
