Worked on the sympy/sympy repository to improve documentation quality and contributor attribution processes. Focused on enhancing the CodeBlock class documentation by correcting a specific typo, ensuring that technical references are accurate and clear for future users and contributors. Updated the .mailmap file to map contributor email addresses, which supports accurate patch provenance and maintains the integrity of the project's contribution history. Utilized Python for understanding code context, applied git for version control, and emphasized documentation best practices. These efforts contributed to repository hygiene and streamlined onboarding, aligning the documentation with established contribution guidelines for the sympy project.
