Worked on the solana-foundation/solana-com repository to enhance course content accessibility by addressing a specific documentation issue. Focused on improving usability for learners, the developer identified and fixed an inaccessible link within the program-architecture.mdx file, updating the Y2K bug explanation URL to a more accessible educational resource. This targeted bug fix ensured that referenced information was available without barriers, aligning external resources with accessibility standards. The work was completed using Markdown and documentation best practices, emphasizing clarity and inclusivity in technical content. Over the month, the contribution centered on refining course materials rather than adding new features or complex code.
