-As of 2020/02/13, A1 (Dockerfile), Dockerfile-Unit-Test, and all three integration test receivers use a base image from o-ran-sc.
-The rmr version is in that base image.
-When version changes are made in that image, rebuilding those 5 containers in the A1 repo will pick it up (or just A1 itself for prod usage).
+A1 (Dockerfile), Dockerfile-Unit-Test, and all three integration test
+receivers use an Alpine base image and install RMR from a base builder
+image. Must update and rebuild all 5 containers in the A1 repo (or
+just A1 itself for production usage).
+
+In addition these items in this repo must be kept in sync:
+
+#. ``rmr-version.yaml`` controls what rmr gets installed for unit
+ testing in Jenkins
+#. ``integration_tests/install_rmr.sh`` is a useful script for a
+ variety of local testing.
