+If you installed `CubicWeb` by cloning the Mercurial forest, then you
+will need to update the environment variable PYTHONPATH to add to it 
+the path to the forest ``cubicweb``.
 
 Add the following lines to either `.bashrc` or `.bash_profile` to configure
 your development environment ::
   
   export PYTHONPATH=/full/path/to/cubicweb-forest

-  export ERUDI_REGISTRY=~/etc/erudi.d/
-  export ERUDI_TEMPLATES=~/hg/

-Cela suppose que le composant erudi que vous développez est dans un
-sous-répertoire de *~/hg/* et que vous avez créé le répertoire *~/etc/erudi.d/*
-pour que `cubicweb-ctl` y place vos instances de test.
+If you installed the debian packages, no configuration is required.
+Your new cubes will be placed in `/usr/share/cubicweb/cubes` and
+your applications will be placed in `/etc/cubicweb.d`.
