Worked on enhancing the developer experience for the Shopify/checkout-sheet-kit-swift repository by delivering a comprehensive update to the preloading feature documentation. Focused on Markdown-based technical writing, the work clarified when and how to use preloading, addressed considerations for flash sales, and explained cache invalidation strategies. The documentation improvements provided practical guidance and operational best practices, aiming to reduce onboarding friction and misconfiguration risks for developers integrating the feature. By improving maintainability and consistency across the repository, the update enabled faster, more predictable integration timelines and supported more reliable checkout experiences through clearer expectations for preloading behavior and usage.
