 ## Mutual authentication with Verifiable Credentials
 
-This section shows an example where the TLS client as well as the TLS server use VCs for authentication. In fact the server selects VC for both client_cert_types and server_cert_types extensions and in the CertificateRequest message sends the did_methods extension with a set of DID methods both endpoints have in common.

+The client sends the did_methods extension along with the server_certificate_type extension set to VC as the first option. The server sends the server_certificate_type set to VC, the client_cert_type set to VC and the CertificateRequest message together with the did_methods extension with a set of DID Methods both endpoints have in common. Both client and server send their Verifiable Credential into their respective Certificate message.
