 <section name="Introduction">
+  <p>
+  Apache Tribes supports an interceptor architecture to intercept both messages and membership notifications.
+  This architecture allows decoupling of logic and opens the way for some very kewl feature add ons.

+<section name="Static Membership">
+  <p>
+   In addition to dynamic discovery, Apache Tribes also supports static membership, with membership verification.
+   To achieve this add the <code>org.apache.catalina.tribes.group.interceptors.StaticMembershipInterceptor</code>
+   underneath the <code>org.apache.catalina.tribes.group.interceptors.TcpFailureDetector</code> interceptor.
+   Inside the <code>StaticMembershipInterceptor</code> you can add the static members you wish to have.
