No, feel free to use the official guide, it's still very, very, very helpful. Yes, you do need to use an unofficial image, but that's just if you have hardware that requires non-free drivers (or blobbed drivers, Guix uses Linux-Libre by default).
Not the best of circumstances, I know, but it works (plus if you really wanted to, they give the derivation details in the release notes so you could just spin up a Guix VM which runs fine with the default image and generate the image yourself).
