+    <p>For POST/PUT requests, the body is available under <code>msg.req.body</code>. This
+       uses the <a href="http://expressjs.com/api.html#bodyParser">Express bodyParser middleware</a> to parse the content to a JSON object.
+    </p>

+       To send JSON encoded data to the node, the content-type header of the request must be set to

+    <p>
+       <b>Note: </b>This node does not send any response to the http request. This should be done with

+       In the case of a Function node, the <a href="http://expressjs.com/api.html#res">Express response documentation</a>
+       describes how this should be done. For example:
+       <pre>msg.res.send(200, 'Thanks for the request ');<br/>return msg;</pre>

+    <p>Save will update an existing object or insert a new object if one does not already exist.</p>
+    <p>Insert will insert a new object.</p>
+    <p>Save and insert either store <b>msg</b> or <b>msg.payload</b>.</p>
+    <p>Update will modify an existing object or objects. The query to select objects to update uses <b>msg.query</b> and the update to the element uses <b>msg.payload</b>.</p>
+    <p>Update can add a object if it does not exist or update multiple objects.</p>
+    <p>Remove will remove objects that match the query passed in on <b>msg.payload</b>. A blank query will delete <i>all of the objects</i> in the collection.</p>
+    <p>You can either set the collection method in the node config or on <b>msg.collection</b>. Setting it in the node will override <b>msg.collection</b>.</p>
+    <p>By default MongoDB creates an <i>_id</i> property as the primary key - so repeated injections of the same <b>msg</b> will result in many database entries.</p>
+    <p>If this is NOT the desired behaviour - ie. you want repeated entries to overwrite, then you must set the <b>msg._id</b> property to be a constant by the use of a previous function node.</p>
+    <p>This could be a unique constant or you could create one based on some other msg property.</p>
+    <p>Currently we do not limit or cap the collection size at all... this may well change.</p>
