For my BumperGoals GitHub repository, I completely overhauled the documentation and presentation to match a professional engineering standard.

First, I fixed the overall layout of the repository’s landing page by completely replacing the basic documentation with a beautifully formatted README file. I added interactive badges at the top, including direct simulation links to both Wokwi project pages so anyone visiting can immediately test out the code and circuits for the robot chassis and the controller.

Second, I integrated high-quality visual renders directly into the documentation. I structured the file to cleanly display my design images side-by-side, perfectly matching the controller shell and its corresponding PCB board layout, as well as the main robot chassis design and the motor assembly view.

Third, I cleaned up and corrected the technical data. I mapped out the exact pin configurations for the dual joysticks and the Arduino Nano into an easy-to-read hardware pin table. I also corrected and clarified the movement logic matrix to clearly show how the mirrored N20 motors handle tank steering when pushing the left joystick for straight lines and the right joystick for sharp spins.

Finally, I added a clear, step-by-step assembly section detailing exactly how to construct both the handheld controller and the robot chassis, ensuring that the repository serves as a complete, production-ready guide for building the physical hardware from scratch.
