+<!-- Processor Documentation ================================================== -->
+<h2>Description:</h2>
+<p>
+    This processor runs bulk updates against MongoDB collections. The flowfile content is expected to be a JSON array with bulk write operations as described in the <a href="https://www.mongodb.com/docs/manual/reference/method/db.collection.bulkWrite/" target="_blank">manual for db.collection.bulkWrite</a>.
+</p>
+<p>
+    You can use all (currently 6) operators described there. The flowfile content is returned as-is. You can merge many operations into one - and get massive performance improvements.
+</p>
+<h2>Example:</h2>
+<p>
+    The following is an example flowfile content that does two things: insert a new document, and update all documents where value of <em>hey</em> is greater than zero.
+</p>
+<code>
+            <pre>
+                [
+                    {"insertOne": {"document": {"ho": 42}}},
+                    {"updateMany": {"filter": {"hey": {"$gt": 0}}, "update": {"$inc": {"hey": 2}}}}
+                ]
+            </pre>
