+# MP carriers
+
+[TOC]
+
+## Overview
+
+There are two settings properties that improve the behaviour of MP carriers.
+
+Both appear in the "Multiplayer Settings" dialogue, from menu "Multiplayer/Multiplayer Settings".
+
+* `/sim/mp-carriers/auto-attach`
+
+    This is true by default.
+    
+    When an MP carriers appear, we automatically enable the matching AI scenerio so that it will
+    be visible to the user.
+
+* `/sim/mp-carriers/latch-always`
+
+    This is not enabled by default.
+    
+    When enabled we force an AI carrier to exactly follow the position and orientation of the MP carrier; this is done by C++ in each frame (otherwise Flightgear uses Nasal to periodically change the AI carrier's velocity to make it approximately follow the MP carrier).
+    
+    This works better as long as multiplayer motion is smooth (e.g. with simple-time).
+    
+    And it also improves behaviour when replaying recordings because the carrier position is replayed exactly the same as when recorded.
