Worked on improving documentation quality for the HarperDB/documentation repository, focusing on enhancing schema definitions to support clearer onboarding. Addressed a specific clarity issue by correcting a typo in the defining-schemas.md file, ensuring that example code is accurate and easy to follow for new users. The update was delivered as a single, traceable commit, emphasizing maintainability and transparency in documentation practices. Utilized Markdown to implement the changes, applying documentation best practices to improve readability and reduce potential confusion. No code features or bug fixes were introduced beyond this documentation enhancement, with the primary goal of supporting self-service learning and onboarding efficiency.
