+Package params defines the simulation parameters in the gaia.
+
+It contains the default weights used for each transaction used on the module's
+simulation. These weights define the chance for a transaction to be simulated at
+any gived operation.
+
+You can repace the default values for the weights by providing a params.json
+file with the weights defined for each of the transaction operations:
+
+	{
+		"op_weight_msg_send": 60,
+		"op_weight_msg_delegate": 100,
+	}
+
+In the example above, the `MsgSend` has 60% chance to be simulated, while the
+`MsgDelegate` will always be simulated.
