 Clients can authenticate using an authentication token.
 The token can be passed to Vagrant Cloud one of two ways:
 
-1. (Preferred) Set the `X-Atlas-Token` header to the value of the authentication token.
+1. (Preferred) Set the `Authorization` header to `"Bearer "` and the value of the authentication token.
 2. Pass the authentication token as an `access_token` URL parameter.
 
 Examples below will set the header, but feel free to use whichever method is easier for your implementation.
 
--> The header name `X-Atlas-Token` is an artifact of Vagrant Cloud's previous project name, "Atlas".
--> This header will be updated in the near future, but `X-Atlas-Token` will continue to be supported for now to ensure backwards-compatibility.
+-> The `X-Atlas-Token` header is also supported for backwards-compatibility.
