+
+global-jjb should be deployed in the ci-management repository's jjb directory as
+a submodule. global-jjb is versioned and tagged in Gerrit so installing,
+upgrading, and rolling back changes should be simple via the Gerrit tag system.

+    # Choose a global-jjb version to install
+    GLOBAL_JJB_VERSION=v0.1.0
+
+    # Add the new submodule to ci-management's jjb directory.
+    # Note: Only needs to be performed once per ci-management repo.
+    cd jjb/
+    git submodule add https://gerrit.linuxfoundation.org/infra/releng/global-jjb

+    # Checkout the version of global-jjb you wish to deploy.
+    cd global-jjb
+    git checkout $GLOBAL_JJB_VERSION

+    # Commit global-jjb version to the ci-management repo.
+    cd ../..
