 # YoutubeTranscript
 
-A Swift library for fetching YouTube video transcripts (captions) programmatically. Supports both standard YouTube videos and Shorts, with robust error handling and async/await support.
+I tried to find a library that fetches YouTube video transcripts for Swift but couldn’t find one, so I made one myself.
+
+This package uses an unofficial YouTube API, so it may break over time if no updates are made.
+The library uses an HTML scraper and the Innertube API to fetch transcripts.
+
+Heavily inspired by [youtube-transcript](https://github.com/Kakulukian/youtube-transcript)
