-The `dsi` message indicates the queue is ready and the user is expected to send
-the entry inputs to start mixing.
+The `dsi` message replies to a `dsq` message that has the Ready field set to 0x01.
+The `dsi` message contains user inputs for mixing along with the outputs and a
+collateral. Once the masternode receives `dsi` messages from all members of the
+pool, it responds with a `dsf` message.
