+# What is this for?
+
+This docker compose set up a primary replica using pull-replication to replicate the data
+over git http across the 2 nodes.
+
+To spin up your environment:
+1) copy the pull-replication artefact to test in te example-setup directory:
+
+```bash
+cp $GERRIT_HOME/bazel-bin/plugins/pull-replication/pull-replication.jar .

+
+```bash
