+h2. How to use with multiple ORM's
 
+Sometimes you need to use multiple ORMs in your application. You can use DatabaseCleaner to clean multiple ORMs, and multiple connections for those ORMs.
+
+<pre>
+  #How to specify particular orms
+  DatabaseCleaner[:active_record].strategy = :transaction
+  DatabaseCleaner[:mongo_mapper].strategy = :truncation
+
+  #How to specify particular connections
+  DatabaseCleaner[:active_record,{:connection => :two}]
+</pre>
+
+Usage beyond that remains the same with DatabaseCleaner.start calling any setup on the different configured connections, and DatabaseCleaner.clean executing afterwards.
+
+Configuration options
+<table>
+  <tr>
+    <th>ORM</th>
+    <th>How to access</th>
+    <th>Notes</th>
+  </tr>
+  <tr>
+    <td>Active Record</td>
+    <td>DatabaseCleaner[:active_record]</td>
+    <td>Connection specified as :symbol keys, loaded from config/database.yml</td>
+  </th>
+  <tr>
+    <td>Data Mapper</td>
+    <td>DatabaseCleaner[:data_mapper]</td>
+    <td>Connection specified as :symbol keys, loaded via Datamapper repositories</td>
+  </th>
+  <tr>
+    <td>Mongo Mapper</td>
+    <td>DatabaseCleaner[:mongo_mapper]</td>
+    <td>Multiple connections not yet supported</td>
+  </th>
+  <tr>
+    <td>Mongoid</td>
+    <td>DatabaseCleaner[:mongoid]</td>
+    <td>Multiple connections not yet supported</td>
+  </th>
+  <tr>
+    <td>Couch Potato</td>
+    <td>DatabaseCleaner[:couch_potato]</td>
