Worked on the Blaizzy/mlx-audio repository to enhance documentation for a new text-to-speech feature, specifically the --lang_code option. Focused on improving the README by providing clear usage guidance and practical examples, including basic generation, voice selection, immediate playback, and saving output to a directory. Employed Markdown for structured documentation and leveraged Git for version control to ensure alignment between code changes and user-facing instructions. This work aimed to streamline onboarding, reduce support needs, and facilitate downstream integration by making the new feature more discoverable and easier to adopt for users familiar with TTS workflows and documentation best practices.
