Worked on enhancing the reqnroll/Reqnroll repository by updating its documentation to declare .NET 9.0 as a supported platform, thereby clarifying compatibility with the latest .NET versions. Focused exclusively on documentation, the update was implemented using Markdown and did not involve any code changes. This approach improved transparency around platform support, aiming to reduce onboarding friction and minimize potential support questions from users. The work demonstrated attention to detail in technical communication and an understanding of the importance of clear documentation in open source projects. The contribution centered on documentation skills and knowledge of .NET platform compatibility requirements.
