gemini
your capsule at gemini://runv.club/~you/
in the terminal: help gemini
Your Gemini capsule is ~/public_gemini, at gemini://runv.club/~you/ You'll need a Gemini client to see it, Lagrange or Amfora for example.
The front page is ~/public_gemini/index.gmi. Gemtext is simple:
# A heading A paragraph is just a line of text. => gemini://runv.club/~you/other.gmi a link * a list item
Files must be readable by others (chmod 644). Edit what is inside ~/public_gemini, but don't delete or replace the folder itself: the server keeps a hold on it, and a new folder won't show up until an admin resyncs it.
