Contributed to the NotDarkn/ultradocs repository by delivering comprehensive documentation enhancements focused on speedrunning strategies for Level 4-1 and Any-4-1. The work involved drafting detailed technical guides in Markdown, introducing new starting strategies, and documenting advanced techniques such as Slam Store Dive and 35 HP Jackhammer UB, each supported by video demonstrations. Terminology was refined by renaming Jackhammer exit to Jackhammer UB, improving clarity for users. The updates also included extensive hyperlink, grammar, and formatting revisions to streamline navigation and readability. This technical writing effort strengthened onboarding resources and ensured more reliable, accessible guidance for the speedrunning community.
