+# Quick Start
+
+In this guide we will set up a general-purpose TLS verifier ( a.k.a. the `Notary`), so that a `Prover` can notarize some TLS data and generate a proof which he then shows to a `Verifier` for selective disclosure.
+
+So this guide will take you through the steps of:
 - starting a `Notary` server
 - running a `Prover` to notarize some web data
 - running a `Verifier` to verify the notarized data
 
-Note that the TLSNotary protocol assumes that the `Notary` is trusted by the `Verifier`. To minimize the trust, the `Verifier` itself can act as a `Notary`.
