Contributed a comprehensive update to the OI-wiki/OI-wiki repository by enhancing the documentation for the pwd command, focusing on cross-platform usage and clarifying its absence in Windows CMD while providing suitable alternatives. The work involved reorganizing and refining the tools/cmd.md file to improve readability and ensure the guidance was accessible to users on different operating systems. Markdown was used extensively for documentation, with remark-lint applied to maintain consistent formatting standards. This update aimed to streamline developer onboarding and reduce support queries by delivering clear, OS-aware instructions, and included collaborative, co-authored commits to reinforce traceability and team workflow.
