 #### How does it works
 
 
-First, We get here mirror repository using a Git clone as an intermediary. As follow, Maintainer get pull from the source repository (official CROCO gitlab or NEMO svn repository) and then git push to the GitLab Legos repository.
 
+First, each user has to download reference svn repository with the good revision associated to the configurations
 
-Each user can retrieve (via the git clone command) a project from the repos (NEMO_CFGS/CROCO_CFGS/TOOLS) on his working environment. The environment here is partitioned, i.e. the user cannot write on  the LEGOS repos, nor modify the official repository of the model, as he doesn't have developper right access.
 
+get svn repos ==> 
 
-> **Note**: It is important to remember that these configurations have been tested and validated on a given cluster, the user can of course test them on another environment, but the documentation is not planned.
