Contributed targeted documentation enhancements to the stylelint/stylelint repository, focusing on improving user understanding and maintainability for two core rules. The work involved clarifying the specificity differences between complex and simple notations in the selector-not-notation rule, as well as expanding the descriptions for the ignoreLonghands and ignoreShorthands options in the declaration-block-no-redundant-longhand-properties rule. These updates aimed to reduce user confusion and streamline onboarding for new contributors. The technical approach centered on precise documentation writing using Markdown, adherence to repository contribution processes, and maintaining cross-rule consistency, resulting in clearer guidance for both end users and future maintainers of the project.
