+## YouTube Cookies
+
+In some environments (VPS, dedicated servers, VPN/WARP containers), YouTube search may fail due to rate limits or bot protection.  
+Providing a valid YouTube cookie file can resolve this issue.
+
+Configure the cookie file in:
+
+`Sounds > CookieFile`
+
+inside your JSON configuration.
+
+---
+
+### How to Get YouTube Cookies
+
+1. Install a browser extension that exports cookies in **Netscape format (`cookies.txt`)**
+   - Chrome: **Get cookies.txt LOCALLY**
+   - Firefox: **cookies.txt**
+
+2. Open https://youtube.com and make sure you are logged in.
+
+3. Use the extension to export cookies for `youtube.com`.
+
+4. Save the file as:
+
+   ```
+   cookies.txt
+   ```
+
+5. Upload it to your server (example):
+
+   ```
+   /app/config/cookies.txt
+   ```
+
+6. Set the path in your configuration:
+
+   ```json
+   {
+     "YoutubeSearch": {
+      "parameters": {
+          "proxy": "",
+          "keywords_banned": [],
+          "cookies": "config/cookies.txt"
+      }
+     }
+   }
+   ```
+
+7. Restart the container after updating the configuration.
+
+8. It's prefered to use **Cloudflare WARP** (recommended for VPS environments), you can run it using:  
+   https://github.com/cmj2002/warp-docker  
+
+   Then configure Torchlight to use the WARP container's socks5 proxy:
+
+   ```yaml
+   "proxy": "socks5://0.0.0.0:PORT"
+   ```
+
+   This routes all requests through WARP, which helps prevent YouTube blocking server IP addresses.
+---
+
+### Notes
+
+- Keep your cookie file private (it contains session authentication data).
+- If YouTube search stops working, export fresh cookies.
+- Do **not** share your cookie file publicly.
