Worked on enhancing the installation guide for the AntaresSimulatorTeam/antares-xpansion repository, focusing on improving the onboarding experience and build reliability for new developers. The primary contribution involved updating documentation written in Markdown to provide clearer, more detailed instructions for configuring dependencies and building the Antares Simulator. Leveraged technical writing skills and knowledge of CMake to ensure the guide accurately reflected current build requirements and reduced setup friction. No bug fixes were addressed during this period, as the work centered on documentation-driven delivery to streamline the setup process and align developer workflows with evolving project standards and technical expectations.
