+You need to have cloned ProxyFS into your GOPATH (i.e. $GOPATH/src/github.com/swiftstack/ProxyFS) for this to work
+
+    vagrant up
+
+Then `vagrant ssh` and you can start services:
+
+`start_and_mount_pfs` - starts Swift (including NoAuth Proxy), ProxyFS, Samba, and NFS... and performs an SMB and NFS mount of CommonVolume
+`start_proxyfs_and_swift` - starts Swift (including NoAuth Proxy) and ProxyFS
+`start_swift_only` - starts Swift (including NoAuth Proxy)
+`unmount_and_stop_pfs` - stops any of the above
+
+The swift source is installed from a git clone in /home/swift/swift
+
+The vagrant user has some env setup to help you
+... but expect most things to require "sudo -E"
