 This will teardown the XOS container set, tell the build system to rebuild
 images, then perform a build and reload the profile.
 
+#### Use ElasticStack or ONOS with the `single` scenario
+
+The single scenario is a medium-weight scenario for synchronizer development,
+and has optional ElasticStack or ONOS functionality.
+
+To use these, you would invoke the ONOS or ElasticStack milestone target before
+the `build` target:
+
+```
+make PODCONFIG=rcord-single.yml config
+make -j4 milestones/deploy-elasticstack
+make -j4 build
+```
+
+or
+
+```
+make PODCONFIG=opencloud-single.yml config
+make -j4 milestones/deploy-onos
+make -j4 build
+```
+
+If you want to use both in combination, make sure to run the ElasticStack
+target first, so ONOS can send logs to ElasticStack.
+
