-# how to configure a cobalt instance for youtube
-if you get various errors when attempting to download videos that are:
-publicly available, not region locked, and not age-restricted;
-then your instance's ip address may have bad reputation.
-
-in this case you have to use disposable google accounts.
-there's no other known workaround as of time of writing this document.
-
-> [!CAUTION]
-> **NEVER** use your personal google account for downloading videos via any means.
-> you can use any google accounts that you're willing to sacrifice,
-> but be prepared to have them **permanently suspended**.
->
-> we recommend that you use accounts that don't link back to your personal google account or identity, just in case.
->
-> use incognito mode when signing in.
-> we also recommend using vpn/proxy services (such as [mullvad](https://mullvad.net/)).
-
-1. if you haven't done it already, clone the cobalt repo, go to the cloned directory, and run `pnpm install`
-
-2. run `pnpm -C api token:youtube`
-
-3. follow instructions, use incognito mode in your browser when signing in.
-i cannot stress this enough, but again, **DO NOT USE YOUR PERSONAL GOOGLE ACCOUNT**.
-
-4. once you have the oauth token, add it to `youtube_oauth` in your cookies file.
-you can see an [example here](/docs/examples/cookies.example.json).
-you can have several account tokens in this file, if you like.
-
-5. all done! enjoy freedom.
-
-### liability
-you're responsible for any damage done to any of your google accounts or any other damages. you do this by yourself and at your own risk.
