 This plugin gives you two CMB field types based on the Select2 script:
 
 1. The `pw_select` field acts much like the default `select` field. However, it adds typeahead-style search allowing you to quickly make a selection from a large list
 2. The `pw_multiselect` field allows you to select multiple values with typeahead-style search. The values can be dragged and dropped to reorder
 
+## Installation
+
+You can install this field type as you would a WordPress plugin:
+
+1. Download the plugin
+2. Place the plugin folder in your `/wp-content/plugins/` directory
+3. Activate the plugin in the Plugin dashboard
+
+Alternatively, you can place the plugin folder in with your theme/plugin. After you call CMB:
+
+```php
+require_once 'init.php';
+```
+
+Add another line to include the `cmb-field-select2.php` file. Something like:
+
+```php
+require_once 'cmb-field-select2/cmb-field-select2.php';
+```
+
