+# Map-controller APIs
+
+Overview of the exposed UBUS API as well as the TR-181 DataModel Operate
+commands, which interact with map-controller.
+
+## UBUS API
+
+APIs exposed over the microbus are used primarily to issue CMDU requests for
+network statistics or triggering operations, such as steering or scanning.
+However, APIs are additionally available to expose data to the TR-181 DataModel
+and debugging, such as steering statistics and network topology information.
