+Use the `--namespace` and `--all-namespaces` flags to control which namespace to view:
+
+```console
+$ svcat get brokers --namespace default
+         NAME          NAMESPACE                              URL                              STATUS
++--------------------+-----------+-----------------------------------------------------------+--------+
+  minibroker                       http://minibroker-minibroker.minibroker.svc.cluster.local   Ready
+  ups-broker           default     http://ups-broker-ups-broker.ups-broker.svc.cluster.local   Ready
+```
+
+You can view only cluster-scoped brokers with the `--scope` flag:
+
+```
+$ svcat get brokers --scope cluster
+         NAME          NAMESPACE                               URL                              STATUS
