+...
+
+Introduction
+------------
+
+This module gives HTTP access to prosody’s storage mechanism. It uses
+normal HTTP verbs and [Basic HTTP
+authentication](http://tools.ietf.org/html/rfc2617), so you could call
+it RESTful if you like buzzwords.
+
+Syntax
+------
+
+To Fetch data, issue a normal GET request
+
+    GET /data[/<host>/<user>]/<store>[/<format>] HTTP/1.1
+    Authorization: <base64(authzid:password)>
+
+OR
+
+    PUT|POST /data[/<host>/<user>]/<store> HTTP/1.1
+    Content-Type: text/x-lua | application/json
+
+    <data>
+
+These map to `datamanager.method(user, host, store, data)`, where choice
+of `method` and its parameters are explained below.
+
