 ## Generative Icons
-Uses a unique and programmatically generated icon for a given service. This is particularly useful when you have a lot of similar services with a different IP or port, and no specific icon. These icons are generated with [ipsicon.io](https://ipsicon.io/). To use this option, just set an item's to: `icon: generative`.
+Uses a unique and programmatically generated icon for a given service. This is particularly useful when you have a lot of similar services with a different IP or port, and no specific icon. These icons are generated with [DiceBear](https://avatars.dicebear.com/), and use a hash of the services domain/ ip for entropy, so each domain will always have the same icon. To use this option, just set an item's to: `icon: generative`.
