Worked on the Alishahryar1/free-claude-code repository to deliver a focused documentation feature aimed at improving onboarding and environment setup. Enhanced the README by providing explicit, shell-specific instructions for setting environment variables using both PowerShell and Bash, ensuring cross-platform compatibility for Windows and Unix-like systems. This update streamlined the first-run experience, reduced setup friction, and enabled faster developer ramp-up by supporting self-service installation. Demonstrated skills in documentation best practices, environment configuration, and scripting, with careful attention to version-control discipline. No bugs were addressed during this period, but outstanding issues were tracked for future sprints to maintain project momentum.
