 This code demonstrates how to use the Crawl4AI library to fetch a single page or multiple pages. The `WebCrawler` is initialized with the path to the database, and the `fetch_page` and `fetch_pages` methods are used to crawl the specified URLs.
 
-Make sure to set the `GROQ_API_TOKEN` environment variable with your Groq API token when using the library.
+Make sure to check the config.py tp set required environment variables.
