There are several ways to browse Gemini sites on your computer:

The slickest and easiest solution is to install Lagrange. It's fast, the interface is clean, and it's available for iOS, Flatpak, and a multitude of other platforms. Even better, it also supports the Gopher & Finger protocols. This is useful because a lot of Gemini server operators also run Gopher & Finger servers. Having all three in one visually-pleasing browser is a great way to take in the ecosystem.

You can install browser extensions to haphazardly duct-tape Gemini support into your browser. If you don't want to install anything, you can use Circumlunar's Gemini Proxy. But I wouldn't recommend either of these options outside emergency use. The whole point of using Gemini is so that you can read plaintext articles without the mammoth memory footprint of modern web browsers. Dedicated Gemini apps are so much faster & smoother. Just install Lagrange and you'll see why people appreciate it.
