+FUSE
+====
+
+To mount Ceph FS in your file systems table as a filesystem in user space, add the
+following to ``/etc/fstab``::
+
+       #DEVICE                                  PATH         TYPE      OPTIONS
+       id={user-ID}[,conf={path/to/conf.conf}] /mount/path  fuse.ceph defaults 0 0
+
+For example::
+
+       id=admin  /mnt/ceph  fuse.ceph defaults 0 0 
+       id=myuser,conf=/etc/ceph/cluster.conf  /mnt/ceph2  fuse.ceph defaults 0 0 
+
+The ``DEVICE`` field is a comma-delimited list of options to pass to the command line.
+Ensure you use the ID (e.g., ``admin``, not ``client.admin``). You can pass any valid 
+``ceph-fuse`` option to the command line this way.
