Worked on improving onboarding documentation for the microsoft/semantic-kernel repository by updating the README.md to clarify that the .env file should be placed in the repository root. This change addressed a common source of confusion for new users, aligning the documentation with standard project structure and reducing ambiguity during setup. The update was implemented using Markdown, with a focus on clear and concise technical writing to enhance the developer experience. The work maintained traceability by referencing the relevant issue and commit, demonstrating attention to documentation quality and process transparency. No bug fixes or additional features were delivered during this period, emphasizing documentation skills.
