During June 2025, the developer enhanced onboarding and deployment workflows for the NIGMS/NIGMS-Sandbox repository by updating SageMaker Notebook and Studio setup documentation. They focused on improving clarity by renumbering steps, correcting image URI and repository name references, and refining instructions for building and deploying custom Docker images. Using Markdown for documentation and shell scripting for deployment guidance, the developer addressed subtle onboarding issues, reducing confusion and potential setup errors. While no major bugs were fixed, the work resulted in more maintainable documentation and a smoother onboarding process, ultimately decreasing support requests and improving the overall deployment experience for new users.
