Worked on enhancing the onboarding experience for the zephyrproject-rtos/zephyr-testing repository by updating the Getting Started Guide’s visual content. Focused on documentation and technical writing, the developer replaced the existing blinky animation image with a more engaging and clear visual using reStructuredText. This targeted improvement aimed to make the documentation more accessible and visually appealing, supporting new users in understanding setup steps more efficiently. Throughout the process, careful attention was given to documentation hygiene and adherence to Git best practices, resulting in clearer guidance and potentially reducing the time required for new contributors to achieve their first successful setup.
