+Introduction
+============
+
+[PKIX over Secure HTTP (POSH)][rfc7711] describes a method of
+securely delegating a domain to a hosting provider, without that hosting
+provider needing keys and certificates covering the hosted domain.
+
+# Setup
+
+This module performs POSH validation of other servers. It is *not*
+needed to delegate your own domain.
