+Quick start instructions:
+
+  - add the following entry to /etc/exports:
+
+    %%CFSD_BOOTSTRAP%% localhost
+
+  - create the default CFS mountpoint (if you want to use a different
+    mountpoint, set the cfsd_mountpoint variable in /etc/rc.conf):
+
+    # mkdir /crypt
+
+  - enable rpcbind, mountd and cfsd in /etc/rc.conf:
+
+      cfsd_enable="YES"
+      mountd_enable="YES"
+
+  - start mountd and cfsd, or restart:

+This is CFS, Matt Blaze's Cryptographic File System.  It provides
+transparent encryption and decryption of selected directory trees.
+It is implemented as a user-level NFS server and thus does not
+require any kernel modifications.
+
+For an overview of how to use it, read "${PREFIX}/share/doc/cfs/notes.ms"
+and the manual pages.  There is a paper describing CFS at:
