During October 2024, Peng Peng focused on enhancing the PP&SAM documentation within the IntensiveCoLearning/english_2nd repository. Peng expanded the pp&sam.md file by adding a new dated entry, detailed vocabulary definitions, and explicit references to applications such as the ling Q app. Using Markdown and leveraging strong documentation skills, Peng clarified terminology by defining key concepts like citing, stating the reasons of, no plumbing, and dealers, thereby improving onboarding and repository hygiene. While no bugs were addressed during this period, the work demonstrated depth in technical writing and a commitment to accuracy, clarity, and discoverability for future contributors.
