1. Download the plugin.
2. Upload the plugin to your wp-content/plugins directory.
3. Activate the plugin.
4. Drag widget to your sidebar.
5. Enter Title, Your Amazon Affiliate ID (affid), and a list of Amazon product ASIN numbers. If you do not enter the amazon affiliate ID it uses mine, so you had better sign up with Amazon before using this widget if you want to make money.

If you are upgrading from a previous version make sure that you go to the widget configuration to check your affiliate Id and list of asins.
