Worked on enhancing documentation quality for the remotion-dev/remotion repository, focusing on the Lambda CLI deploy function’s runtime-preference feature. The work involved standardizing terminology, such as updating the default from 'prefer-cjk' to 'cjk' and 'prefer-apple-emojis' to 'apple-emojis', to ensure consistency across documentation. Markdown was used extensively to clarify package version requirements and update version availability information, improving accuracy for users referencing deployment docs. The approach emphasized documentation hygiene, addressing typos and inconsistencies in lambda/cli/functions/deploy guides. No user-facing features or bug fixes were introduced, with all efforts concentrated on documentation and process clarity using documentation skills.
