During December 2024, Andy Fu focused on enhancing documentation quality for the damichers/apuntes-si repository by refactoring the Sistemas de Numeración section. He improved the document’s readability and organization through careful application of Markdown formatting, including structured headings and bullet points to clearly separate the introduction from the various numbering systems. Andy’s work centered on content formatting and documentation, ensuring that the technical material is easier to navigate and maintain. While the scope was limited to a single feature and did not involve bug fixes, the changes support faster onboarding for new contributors and streamline ongoing documentation updates within the project.
