 In the above example, we're registering both **Cookie** and **JWT Bearer** auth schemes and in the endpoint we're saying **only JWT Bearer** auth scheme should be used for authenticating incoming requests to the endpoint. You can specify multiple schemes and if an incoming request isn't using any of the said schemes, access will not be allowed.
 
-**NOTE:** When registering multiple auth schemes, you will have to do it yourself without the help of the convenient wrapper methods supplied by FastEndpoints.
+Here's an example of how you'd create a custom auth scheme which would combine both cookie and jwt auth when using the wrapper methods offered by FastEndpoints:
