+First make sure you have registered [hapi-mongodb](https://github.com/Marsup/hapi-mongodb)
+with the server.  Then register hapi-mongodb-collections and specify the collections you want to make available directory from your server object.
+
+## Example
+
+```javascript
+const plugin = require('hapi-mongodb-collections');
+await server.register({
+  plugin,
+  options: {
+    collections: [
+      'myCoinCollection',
+      'myShellCollection',
+      'myStampCollection'
+    ]
+  }
+});
+```
+   will make it possible to do:
+
+```javascript
+await server.myCoinCollection.find({ type: 'dimes' });
+```
+
+## Options
 
 Options:
-  - `collections` - Array of collection names.
+- __collections__ (required)
+  An array of collection names.
+- __namespace__
+  If you want to put your collections under a namespace, you can.  So for example passing:
+  ```javascript
+  {
+    collections: [
+      'myCoinCollection'
+    ],
+    namespace: 'collections'
+  }
+  ```
+   in your plugin options will let you make queries like so:
+
+   ```javascript
+    server.collections.myCoinCollection.find({ type: "dimes" })
+   ```
