Worked on the fleetdm/fleet repository to enhance contributor experience and code quality by updating the Contributor Guidelines and Development Checklist in the README. Focused on documentation and process improvements, the update clarified coding standards, testing protocols, and submission processes, aligning them with automated checks and quality assurance expectations. Used Markdown to expand documentation, specifying validation steps, manual QA checks, and security considerations such as SQL injection prevention. The checklist now includes GitOps and deployment requirements, supporting governance and release readiness. These changes improved onboarding and review efficiency by providing explicit, checkable criteria for contributors, reducing friction in pull request reviews.
