+1. **Download the YouTube Cookies locally**
    - Follow the instruction provided [here](https://github.com/yt-dlp/yt-dlp/wiki/Extractors#exporting-youtube-cookies) to download the YouTube cookies.

+2. **Convert cookie file content to `.env` file locally**
     - Simple copy paste will not work due to special characters
     - So, we will use the `cookies_to_env` function.
       - Uncomment the `# Convert cookie file to env and save locally`  section and run the code
     - Remember to comment the code once the `.env` file is updated.
 3. **Set up or Update the Secrets in HF**
-   - Copy the the `.env` content (only the value, and not the key) and paste it inside the Secrets (Private) > `FIREFOX_COOKIES` in Hugging Face space.
