Make a pull request (PR).
Upon successful review, someone will approve the PR in the review thread. A reviewer with merge power may merge the PR with or without an approval from someone else. Or they may wait a business day to get further feedback from other reviewers.
The ansible-service-broker community uses a spec process when introducing a major feature in order to encourage collaboration and building the best solution.
Major features are things that take about 2 weeks of development and introduce disruptive changes to the code base.
Start the spec process by reviewing the spec template. Use this document to guide how to write a spec. Then, submit it as a pull request where the community will review the plan. The spec process will require two approvals from the community before merging.
