+## Webpage dashboard
+
+Another available (but not default) dashboard is the webpage dashboard. The webpage dashboard allows you to add and embed a webpage to your dashboard.
+This could be a web page from the internet or a local web page from a local
+machine or device like your router or NAS.
+
+<img class="no-shadow" src='/images/blog/2024-04/dashboard-webpage.png' alt='Screenshots showing addition of a new webpage dashboard to Home Assistant, embedding the Home Assistant website.'>
+
+This dashboard replaces the old iFrame panel (`iframe_panel`). If you have
+existing panels configured in your YAML configuration, Home Assistant will
+automatically migrate them to the new webpage dashboard on upgrade.

+
+Note that not every webpage can be embedded due to security restrictions that
+some sites have in place. These restrictions are enforced by your browser and prevent
+embedding them into a Home Assistant dashboard.

 ## Creating a new dashboard
 
 The default **Overview** dashboard updates itself when you add new devices, as long as you do not edit the default dashboard. If you want a customized dashboard, it is recommended not to change the **Overview** dashboard, but to create a new dashboard instead.
