Regis Terrier developed a user-facing Infrastructure as Code (IaC) introduction PDF for the gammapy-meetings repository, targeting onboarding and knowledge transfer during a coding sprint. The work focused on creating clear, accessible documentation rather than modifying code, leveraging Markdown and PDF generation tools to produce a resource that explains IaC concepts to new contributors. All changes were managed through a single, traceable commit, ensuring reproducibility and transparency. While the scope was limited to documentation, the artifact addressed a real need for structured IaC onboarding. The work demonstrated attention to documentation quality and repository hygiene, though it did not involve direct software development.
