+## Important notes:
 
 - We need to remove the local cache between requests. See https://github.com/rhd-gitops-example/services/issues/20. Until then, add `rm -rf ~/.promotion/cache; ` before subsequent requests.
 - New pull requests need new branches (i.e you cannot run the same command twice). Add `--branch [unique branch name]` before submitting further promotion PRs. See https://github.com/rhd-gitops-example/services/issues/21.
 - See https://github.com/rhd-gitops-example/services/issues/19 for an issue related to problems 'promoting' config from a source repo into a gitops repo.

+## Release process
