Gemini is a new application-level internet protocol for the distribution of arbitrary files, with some special consideration for serving a lightweight hypertext format which facilitates linking between files. You may think of Gemini as “the web, stripped right back to its essence” or as “Gopher, souped up and modernised just a little”, depending upon your perspective (the latter view is probably more accurate).
