Worked on enhancing developer documentation for the Ac-Wiki/AcWiKi repository, focusing on streamlining onboarding and reducing installation issues. Addressed a documentation typo related to VSCode terminal shortcuts and introduced a practical tip for configuring a pip mirror, which helps mitigate download and timeout problems during package installation. The improvements were implemented using Markdown, leveraging strong documentation skills to clarify setup instructions and minimize support requests. By refining the onboarding process and providing actionable guidance, the work contributed to a more reliable and efficient development environment, ensuring that new contributors can set up their tools with fewer obstacles and greater confidence.
