Contributed to the InnerSourceCommons/innersourcecommons.org repository by developing comprehensive documentation to support the ISC Summit 2025. Focused on event planning and technical writing, the work centered around creating a Markdown-based inclusion and accessibility guide that outlines the code of conduct, scholarship opportunities, venue accessibility, health and safety protocols, and organizer contact details. This documentation aimed to enhance accessibility compliance and provide clear, centralized guidelines for both attendees and organizers, reducing ambiguity and improving event readiness. By leveraging Markdown and applying event planning expertise, the contribution streamlined contributor onboarding and ensured that essential information was easily accessible for the upcoming summit.
