+### Retrieving an avatar
+
+You can retrieve the avatar from a Nomi with either a Nomi object, or their corresponding UUID.
+
+```php
+/** @var \Nomiai\PhpSdk\NomiAI $sdk **/
+/** @var \Nomiai\PhpSdk\Resources\Nomi $nomi **/
+
+$avatar = $sdk->getAvatarFromNomi($nomi);
+
+// Or via the UUID:
+$avatar = $sdk->getAvatar($nomi->uuid);
+
+/*
+ * Avatar is an object that might get more functionality down the line. For now, 
+ * to get the underlying .webp image, access the avatar property.
+ */
+$webp = $avatar->avatar;
+
+// You can also retrieve the underlying image by casting the object to a string.
+$image = (string) $avatar;
