Thanks !
The equivalent gemini capsule page of the link in my previous post (https://villepreux.net/about/?format=txt) can be found here : gemini://unbon.cafe/villapirorum/about
But you'll need a client/browser suporting it (I'm using Lagrange : https://gmi.skyjake.fi/lagrange)
If you're interested by the gemini protocol : https://geminiprotocol.net
Edit: Lagrange is available on Android and supports Gopher
