During October 2024, Peng Peng focused on enhancing the PP&SAM documentation within the IntensiveCoLearning/english_2nd repository. Their work centered on expanding the pp&sam.md file by adding a new dated entry, clarifying terminology, and explicitly referencing related applications such as the ling Q app. Using Markdown and leveraging strong documentation skills, Peng Peng introduced precise vocabulary definitions and explanations for terms like “citing” and “no plumbing,” aiming to improve onboarding and repository clarity. No bugs were addressed during this period, as the primary contribution was a single feature update that deepened the documentation’s accuracy, discoverability, and technical completeness.
