+=====================================
+OpenStack Shared File Systems service
+=====================================
+
+The OpenStack Shared File Systems service (manila) provides file
+storage to a virtual machine. The Shared File Systems service
+provides an infrastructure for managing shares and provides access
+to shares to instances. The service also enables management of share
+types as well as share snapshots if a driver supports snapshots.
+
+The Shared File Systems service consists of the following components:
+
+manila-api
+  Accepts API requests and routes them to the manila-share for
+  action.
+
+manila-share
+  Interacts directly with the Shared File Systems service and processes
+  such as the manila-scheduler. It also interacts with these processes
+  through a message queue. The manila-share service responds to read
+  and write requests sent to the Shared File Systems service to maintain
+  state. It can interact with a variety of storage providers through a
+  driver architecture.
+
+manila-scheduler daemon
+  Selects the optimal storage provider node on which to create the
+  share. A similar component to the cinder-scheduler.
+
+Messaging queue
+  Routes information between the Shared File Systems processes.
