 Synchronizing the Route Layer with Indexes

 decide how to synchronize the two instances.
 
-Resolving Synchronization Differences
--------------------------------------
+To quickly sync the local and remote instances we can use the `RouteLayer.sync`
+method. This method is equivalent to the `auto_sync` strategy specified when
+initializing the `RouteLayer` object. So, if we assume our local `RouteLayer`
+object contains the ground truth routes, we would use the `local` strategy to
+copy our local routes to the remote instance.
 
-The first step in resolving synchronization differences is to understand the

+
+    rl.sync(sync_mode="local")
+
+After running the above code, we can check whether the local and remote
+instances are synchronized by rerunning `rl.is_synced()`, which should now
+return `True`.

+Investigating Synchronization Differences

+We may often need to further investigate and understand *why* our local and
+remote instances have become desynchronized. The first step in further investigation and resolution of synchronization

 `RouteLayer.get_utterance_diff` method.
