Raphaël Pourcelot enhanced the developer experience for the Thorlabs MCLS1 laser service in the spacetelescope/catkit2 repository by updating and streamlining its documentation. He focused on clarifying configuration details, properties, and control commands, ensuring that technical information was both accessible and precise. Using reStructuredText and leveraging his skills in technical writing and software configuration, Raphaël removed outdated content, such as an unused note section, to reduce confusion and improve maintainability. His work, delivered through two well-documented commits, provided clear guidance for future developers and contributed to a more organized and user-friendly documentation structure within the project.
