+From version 2.x this tool supports the usage of NFS mounted name-volumes, which
+gives faster file synchronisation during composer install and cache clear etc.
+
+It comes with a command `nfs:enable` that exports the users (yours) home directory
+through NFS to localhost, so docker can map directories into the containers. It also 
+requires some changes to the docker-compose.yml files which have been updated
+to support NFS.
+
+If your project don't want to use NFS mounts you simply can remove the `nfsapp`
+volume and change the mappings back to `./` in the docker-compose.yml files.
