Worked on the ebookfoundation/free-programming-books repository to update the Hacktoberfest badge in the README, ensuring it accurately reflected the year 2025 for ongoing contributor engagement. The approach focused on precise documentation changes using Markdown, maintaining repository branding and readiness for Hacktoberfest participants. All updates were tracked through Git commits and linked to the relevant issue for transparency and traceability. No functional code was altered, preserving the stability of the repository while keeping documentation current. Demonstrated skills in open source contribution workflows, documentation best practices, and version control, delivering a targeted, low-risk change that supports the community’s annual participation efforts.
