 ### Authentication
 
-If you want to use command endpoints such as `/api/v1/cars/:CarID/command/:Command` and `/api/v1/cars/:CarID/wake_up`, you need to add authentication to your request.
+If you want to use command or logging endpoints such as `/api/v1/cars/:CarID/command/:Command`, `/api/v1/cars/:CarID/wake_up`, or `/api/v1/cars/:CarID/logging/:Command` you need to add authentication to your request.
 
 You need to specify a token yourself (called **API_TOKEN**) in the environment variables file, to set it. The token has the requirement to be a minimum of 32 characters long.
