If you’re a viewer, you don’t have to install anything. If you’re a streamer and want to enable GWENT Observer for your audience, here’s how you do it:
Visit the official GWENT Observer page on Twitch.
Click the “Install” button.
You’ll be asked to merge your Twitch account with your GOG.COM account via a pop-up window. If you don’t have a GOG.COM account, you can create one free.
That’s it! GWENT Observer is now installed and ready for use.
