Worked on improving the documentation for the TanStack/store repository, focusing on enhancing onboarding clarity and maintaining consistency across guides. Addressed a specific issue in the Quick Start guide by correcting a terminology error, changing 'Previous Deferred Value' to 'Previous Derived Value' to better reflect the intended concept. This update was implemented using Markdown, leveraging strong documentation skills to ensure accuracy without altering any functional code, thereby preserving release stability. The work contributed to reducing potential support queries and smoothing the onboarding process for new users, while also aligning terminology to facilitate future localization and maintain high documentation standards.
