Worked on enhancing the statsig-io/docs repository by updating the ID List Segments documentation to provide clearer guidance for users managing ID list segments. Focused on improving the add-id-list.md file, the work clarified the process of creating an ID list segment, including toggling between 'Conditional' and 'ID List' modes and detailed instructions for uploading CSV files. New sections were introduced to explain the concept of an ID list and to outline methods for managing IDs both manually and through bulk actions. The update was implemented using Markdown and emphasized technical writing and documentation skills to improve user understanding.
