This text provides a step-by-step guide on how to add captions and subtitles to HTML5 videos using Deepgram's transcriptions. It begins by explaining the process of generating transcriptions with Node.js, which is then used to create a WebVTT file for the video. The next steps involve setting up an HTML <video> element and adding a <track> element within it to represent the caption file. The text also explains how to add multiple subtitle tracks in different languages. Finally, it encourages readers to reach out on Twitter or provide feedback through GitHub discussions.
