In September 2025, Alex Welborn updated the ID List Segments documentation in the statsig-io/docs repository, focusing on clarifying the process for creating and managing ID list segments. Alex revised the add-id-list.md file to provide step-by-step guidance on toggling between 'Conditional' and 'ID List' modes and included detailed instructions for uploading CSV files. The update introduced new sections explaining the concept of ID lists and methods for managing IDs both manually and in bulk. This work leveraged Markdown for documentation and emphasized clear, user-focused communication, resulting in a more accessible and maintainable resource for Statsig’s documentation users.
