During September 2025, Chris Williams updated documentation in the NSO-developer/nso-gitbook repository to reflect a new directory structure and permissions guidance for security programs such as cmdptywrapper and epam. Using Markdown and technical writing skills, Chris revised instructions to ensure accuracy in directory paths, permissions, and ownership, directly addressing requirements from ENG-38165 and GITBOOK-294. The work improved the reliability of onboarding and reduced the risk of misconfiguration by aligning documentation with the latest repository changes. While the scope was focused, the updates enhanced maintainability and consistency for teams relying on up-to-date security program documentation and operational guidance.
