Worked on enhancing contributor experience and documentation quality in the noncelab/coconut_wallet repository by updating the CONTRIBUTING.md file. Focused on improving onboarding for external contributors, the work involved correcting a typo in the git hooks setup instructions and clarifying the formatting command to reduce ambiguity during pull request reviews. Emphasized clear communication and traceability by referencing the specific commit associated with the documentation update. Utilized Markdown for documentation and applied skills in technical writing to align project guidelines with established contribution standards. The changes aimed to support consistent workflows and streamline the contribution process for both new and existing collaborators.
