In the OOM QuickStart and User Guide the installation procedure describes the cloning of the OOM repo with this command:

git clone -b casablanca http://gerrit.onap.org/r/oom

The branch "casablanca" is a floating label, which reflect the ONAP component versions in the latest casablanca development state, not the release versions.

Instead it should be described, what is the versioning schema in ONAP and how to select the right version, e.g.:

Casablanca Versions:
3.0.0-ONAP - Casablanca Release (31.11.2018)
3.0.1-ONAP - Casablanca Maintenance Release (31.01.2018)
casablanca  - latest Casablanca development version

{{and in the actual OOM clone command:
}}

git clone -b <version> http://gerrit.onap.org/r/oom
