+## VoiceRoleSync
+
+VoiceRoleSync directs the bot to apply specific roles to users when they are listening in to a voice channel.
+
+Sample within a [server definition](serverdef.html):
+```
+"VoiceRoleSync": {
+	//"1000001::General": "1000002::In General VC",
+	//"1000003::Video Games": "1000004::In Gaming VC"
+	"1000001": "1000002",
+	"1000003": "1000004"
+}
+```
+
+### Definition structure
+A list of voice channels and their respective roles are defined in a `VoiceRoleSync` object. They are defined as JSON properties, with the name portion (before the colon) representing the voice channel and the value portion (after the colon) representing the role to be associated.
+
+At the moment, only voice channel and role ID values are accepted in this configuration. EntityList-like names will be supported at a later date.
