 We had need of a combobox at work and after looking around at the available options I was not happy with any of them.  The project had all it's styling based on Twitter's Bootstrap, so building on that made sense.
 
+## How to install it
+
+You can install this plugin one of two ways.
+
+#### 1. Manual download
+
+Previously, this was the only way to install the plugin. You will need two files included in your HTML in order for this to work:
+
+1. js/bootstrap-combobox.js
+2. css/bootstrap-combobox.css
+
+#### 2. Bower install
+
+This plugin is now in bower! If you've already installed bower on your machine, simply use the command:
+
+```
+bower install bootstrap-combobox
+```
+
+This will install the plugin to your bower_components folder. For more information please see http://bower.io/
+
 ## How to use it
 
 The dependencies are the Bootstrap stylesheet(CSS or LESS).  Include it and then the stylesheet(CSS or LESS) and javascript.
