+#summary HTTP access to prosody’s storage mechanism
+
+= Introduction =
+
+This module gives HTTP access to prosody’s storage mechanism.  It uses normal HTTP verbs and [http://tools.ietf.org/html/rfc2617 Basic HTTP authentication], 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.
+
+== Verbs ==
+
+||*Verb*||*Meaning*                      ||*datamanager method*        ||
+||`GET` || Just fetch data               || `load()` or `list_load()`  ||
+||`PUT` || Replace all data in the store || `store()                   ||
+||`POST`|| Append item to the store      || `list_append()`            ||
+
+Note: In a `GET` request, if `load()` returns `nil`, `list_load()` will be tried instead.
+
+== Fields ==
+
+||*Field*||*Description*||*Default*||
+||`host`||Which virtual host to access||Required. If not set in the path, the domain-part of the authzid is used.||
+||`user`||Which users storage to access||Required. If not set in the path, uses the node part of the authzid.||
+||`store`||Which storage to access.||Required.||
+||`format`||Which format to serialize to. `json` and `lua` are supported. When uploading data, the `Content-Type` header is used.||`json`||
+||`data`||The actual data to upload in a `PUT` or `POST` request.||`nil`||
+
+Note: Only admins can change data for users other than themselves.
+
+== Example usage ==
+
+Here follows some example usage using `curl`.
+
+Get your account details:
+
+{{{
+	curl http://prosody.local:5280/data/accounts -u user@example.com:secr1t
+	{"password":"secr1t"}
+}}}
+
+Set someones account details:
+
+{{{
+	curl -X PUT http://prosody.local:5280/data/example.com/user/accounts -u admin@host:r00tp4ssw0rd --header 'Content-Type: application/json' --data-binary '{"password":"changeme"}'
+}}}
