+ *
+ * \section intro_sec Introduction
+ *
+ * This is the developer documentation of the reference client for an experimental new digital currency called Agrarian (http://www.agrarian.org),
+ * which enables instant payments to anyone, anywhere in the world. Agrarian uses peer-to-peer technology to operate
+ * with no central authority: managing transactions and issuing money are carried out collectively by the network.
+ *
+ * The software is a community-driven open source project, released under the MIT license.
+ *
+ * \section Navigation
