+
+  Pre-requisites:
+  1) have SeaweedFS master and volume servers running
+  2) have a "weed filer" running
+  These 2 requirements can be achieved with one command "weed server -filer=true"
+
+  This uses github.com/seaweedfs/fuse, which enables writing FUSE file systems on
+  Linux, and OS X.
+
+  On OS X, it requires OSXFUSE (http://osxfuse.github.com/).
