+## Storage
+
+### Manage the IDE controller
+
+In case the VM doesn't have an IDE controller you can use the storagectl command to add one:
+
+```javascript
+virtualbox.storage.addCtl({
+	vm: "machine_name",
+	device_name: "IDE", //optional
+	type: "ide" //optional
+}, function(){
+	console.log('Controller has been added!');
+})
+```
+
+### Attach a disk image file
+
+Mount an ISO file to the added controller:
+
+```javascript
+virtualbox.storage.attach({
+	vm: "machine_name",
+	device_name: "IDE", //optional
+	port: "ide", //optional
+	device: "0",
+	type: "0",
+	medium: "X:\Folder\containing\the.iso"
+}, function(){
+	console.log('Image has been mounted!');
+})
+```
+
+The _medium_ parameter of the options object can be set to the **none** value to unmount.
