+<h1><a href="#">Keycloakify </a> Storybook</h1>
+
+<p>
+This website showcases all the Keycloak user-facing pages that can be customized using Keycloakify.
+The storybook serves as a comprehensive reference to help you determine which pages you would like to personalize.
+Keep in mind that customizing the <a href="https://github.com/keycloakify/keycloakify-starter/blob/main/src/keycloak-theme/login/Template.tsx"><code>Template</code></a> component alone will already cover 90% of your customization needs.
+</p>
+
+<p>
+If you discover that a page you wish to customize is not currently supported by Keycloakify, don't worry. 
+Simply refer to <a href="https://docs.keycloakify.dev/limitations#i-have-established-that-a-page-that-i-need-isnt-supported-out-of-the-box-by-keycloakify-now-what">this documentation page</a> for further assistance.
