+## Push remote branch
+
+The deployment playbooks are cloning the monorepository on target hosts, using your current local git branch name. If the branch does not exists on remote, you need to push it.
+
+```
+git push
+```
+
+Alternatively, if there are no changes except the playbooks, you can use the `master` branch:
+
+```
+CIRCLE_BRANCH=master molecule test
+```
+
+In this case `master` branch will be used as a codebase for Monitor, UI, Oracle and Contracts deployed by your local playbook.
+
 ## Run the tests
