Sean Privett enhanced the ministryofjustice/modernisation-platform repository by updating the Runbook documentation to clarify out-of-hours contact procedures. He focused on improving the readability of runbook.html.md.erb using HTML and Markdown, introducing proper line breaks and consolidating support contact methods to email or PagerDuty. By removing redundant criticality information, Sean reduced confusion and improved the accuracy of support instructions for incident response. The work was delivered as a single, well-documented feature, with changes traceable via a dedicated commit. This contribution demonstrated a methodical approach to documentation, prioritizing clarity and maintainability, though it did not involve bug fixes or broader feature development.
