Worked on enhancing documentation for the ministryofjustice/modernisation-platform repository, focusing on clarifying out-of-hours contact procedures within the Runbook. Updated the runbook.html.md.erb file using HTML and Markdown to improve readability by introducing proper line breaks and consolidating support contact methods to email or PagerDuty. Removed redundant criticality information to reduce confusion and ensure more accurate support instructions for incident response. The documentation changes were carefully tracked and committed for traceability. This work emphasized clear communication and maintainability, addressing a specific need for streamlined support processes without introducing new features or bug fixes during the one-month contribution period.
