Worked on the excaliburjs/Excalibur repository to enhance documentation quality, focusing on the Custom Graphics Tutorial. Addressed a documentation bug by correcting a typo related to anti-aliasing and ensured the file adhered to formatting standards by ending with a newline. The work was implemented using Markdown and leveraged technical writing skills to improve clarity and consistency for contributors. No code changes were required, as the effort centered on reducing onboarding friction and supporting clear contributor guidelines. This targeted documentation update aimed to minimize user confusion and streamline the learning process for new developers engaging with the Excalibur project.
