+#### Re-building Containers
+
+By default, container images are not rebuilt if they already exist in the development
+environment.  (NOTE: The `xos_core` container is an exception; it is always rebuilt.)
+To force the development loop to rebuild and redeploy specific containers, add
+`rebuild: true` in the appropriate place as described below.
+
+For service synchronizers, add `rebuild: true` to the service's entry in the `xos_services`
+list in the profile manifest.
+
+For GUI extensions, add `rebuild: true` to the extension's entry in the `enabled_gui_extensions`
+list in the profile manifest.
+
+For all other containers, add `rebuild: true` to the container's entry in the `docker_images`
+list in the XOS repo's `group_vars/all` file.
