-### About synced folders
-
-Due to a limitation related to the Debian boxes, VirtualBox synced folders
-cannot be enabled. Vagrant uses `rsync` instead to upload the current folder
-into the VM at `/vagrant`. But this only occurs once each time you run
-`vagrant up` or `vagrant reload`. However you can ask Vagrant to automatically
-resync when changes occur in the host with the `vagrant rsync-auto` command.
-Please note that this is a **one-way** synchronization.
