+Kathmandunet is a test network which runs the Kathmandu protocol.
+Kathmandunet will run until Kathmandu is refused through the amendment process
+or (accepted and then) replaced by another protocol on Mainnet.
+
+On Kathmandunet, some constants differ from Mainnet.
+This results in a faster chain than Mainnet.
+See :ref:`protocol constants <protocol_constants>` to learn how to find out their values.

 If you did not initialize your node configuration, or if your configuration
 file contains no ``network`` field, the node assumes you want to run Mainnet.
 You can use the ``--network`` option with ``tezos-node run`` to make sure
