+## Troubleshooting
+
+The default search engine for YouTube Analyzer is `youtubesearchpython`. But this component [is not supported anymore](https://github.com/alexmercerind/youtube-search-python/issues/189) by its maintainers and can have errors. Therefore, it is recommended to use YouTube Analyzer with YouTube API. Just set your YouTube API key in settings.
