CONTRIBUTING.md

+# Contributing
+
+Thanks for contributing to this repository!
+
+This repository follows the following conventions:
+
+* [Semantic Versioning](https://semver.org/)
+* [Keep a Changelog](https://keepachangelog.com/)
+* [Conventional Commits](https://www.conventionalcommits.org/)
+
+Development requires the Kubernetes CLI tool as well as a local Kubernetes cluster. [KIND](https://github.com/kubernetes-sigs/kind) is recommended as a lightweight local option for standing up Kubernetes clusters.
+
+To contribute a change:
+
+1. Create a branch on the cloned repository with a descriptive name, prefixed with your name. For example, `gd/add-ingress` is an appropriate branch name.
+2. Make the changes in code.
+3. Write tests using [KUTTL](https://kuttl.dev) and [Conftest](https://conftest.dev)
+4. Make commits using the [Conventional Commits](https://www.conventionalcommits.org/) format. This helps with automation for changelog. Update `CHANGELOG.md` in the same commit using the [Keep a Changelog](https://keepachangelog.com). Depending on tooling maturity, this step may be automated.
+5. Open a merge request using one of the provided templates. If this merge request is solving a preexisting issue, add the issue reference into the description of the MR.
+6. During this time, ensure that all new commits are rebased into your branch so that it remains up to date with the `development` branch.
+7. Wait for a maintainer of the repository (see CODEOWNERS) to approve.
+8. If you have permissions to merge, you are responsible for merging. Otherwise, a CODEOWNER will merge the commit.
