+# LlamaIndex Readers Integration: Youtube-Metadata
+
+```bash
+pip install llama_index.readers.youtube_metadata
+```
+
+This loader fetches the metadata of Youtube videos using the Google APIs. (https://www.googleapis.com/youtube/v3/videos?part=snippet,statistics&id={videos_string}&key={api_key}). You must have a Google API key to use.
+
+Transcripts of the text transcript of Youtube videos is fetched using the `youtube_transcript_api` Python package.
+
+## Usage
+
+Simply pass an array of YouTube Video_ID into `load_data`.
+
+```python
+from llama_index.readers.youtube_metadata import YoutubeMetaData
+
+api_key = "Axxxxx" # youtube API Key
+
+video_ids = ["S_0hBL4ILAg", "a2skIq6hFiY"]
+
+youtube_meta = YoutubeMetaData(api_key)
+details = youtube_meta.load_data(video_ids)
+```
+
+This can be combined with the YoutubeTranscriptReader to provide more information for RAG AI inquiries.
+
+```python
+from llama_index.readers.youtube_transcript import YoutubeTranscriptReader
+from llama_index.readers.youtube_metadata import YoutubeMetaData
+
+video_ids = ["S_0hBL4ILAg", "a2skIq6hFiY"] # Example video IDs
+yt_metadata = YouTubeMetaData(api_key=api_key)
+print("Testing YouTubeMetaData...")
+print(yt_metadata.load_data(video_ids))
+
+yt_meta_transcript = YouTubeMetaDataAndTranscript(api_key=api_key)
+print("Testing YouTubeMetaDataAndTranscript...")
+print(yt_meta_transcript.load_data(video_ids))
+```
+
+The Video_id for youtube videos is right in the URL. In this URL: https://www.youtube.com/watch?v=a2skIq6hFiY&t=60s
+
+The video_Id is 'a2skIq6hFiY&t'.
