+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Device tracker platform that supports scanning a FRITZ!Box router for device
 presence.
 
-Configuration:
-
-To use the fritz tracker you have to adapt your configuration.yaml by
-using the following template:
-
-device_tracker:
-  platform: fritz
-  host: YOUR_ROUTER_IP
-  username: YOUR_ADMIN_USERNAME
-  password: YOUR_ADMIN_PASSWORD
-
-
-Description:
-
-host
-*Optional
-The IP address of your router, e.g. 192.168.0.1.
-It is optional since every fritzbox is also reachable by using
-the 169.254.1.1 IP.
-
-username
-*Optional
-The username of an user with administrative privileges, usually 'admin'.
-However, it seems that it is not necessary to use it in
-current generation fritzbox routers because the necessary data
-can be retrieved anonymously.
-
-password
-*Optional
-The password for your given admin account.
-However, it seems that it is not necessary to use it in current
-generation fritzbox routers because the necessary data can
-be retrieved anonymously.
+For more details about this platform, please refer to the documentation at
