+# Wii Shop Extension
+
+[![Download for Firefox](https://corbin.io/img/firefox-button.png)](https://addons.mozilla.org/en-US/firefox/addon/wii-shop-channel/)
+
+This is a browser extension that plays the [Wii Shop Channel theme](https://www.youtube.com/watch?v=yyjUmv1gJEg&t=1s) in the background when you visit a shopping website. The list of detectable websites is in `js/site-list.js`.
+
+The extension only requires two permissions: [Tabs](https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/tabs), to check the URL of the currently-active tab, and [Notifications](https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/user_interface/Notifications), to show a message after the extension is installed.
+
+**This extension is not developed by, or affiliated with, Nintendo in any way.**
