I have launched a Gemini site which you can access using this link: gemini://arrayinamatrix.xyz/
This link will take you nowhere if you don't have a browser/client that is compatible with the Gemini protocol. I recommend the Kristall browser which can access not only Gemini sites but also other web-pages using HTTP, HTTPS, Gopher and Finger. Like always, there are other clients you can use. You can visit sites using Gemini using a proxy like this one.

I have Mirrored my website and the Arch Linux wiki on Gemini:
