 In mutual TLS (mTLS), the client and the server authenticate each other. gRPC
 allows users to configure mutual TLS at the connection level.

 In normal TLS, the server is only concerned with presenting the server
 certificate for clients to verify. In mutual TLS, the server also loads in a
-list of trusted CA files for verifying client presented certificates with.

 In normal TLS, the client is only concerned with authenticating the server by
 using one or more trusted CA file. In mutual TLS, the client also presents its
-client certificate to the server for authentication. This is done via setting
+client certificate to the server for authentication. This is done by setting
 [`tls.Config.Certificates`](https://pkg.go.dev/crypto/tls#Config.Certificates).
