Simply place all the relevant site files in ~/public_html for HTTP & ~/public_gemini for Gemini. This will be the root directory for your website/capsule. For example, if a user foo wanted a site, they would create /home/foo/public_html/index.html. A file /bar in foo's user site would be located at /home/foo/public_html/bar.
User sites for HTTP are rendered on the URL foo.vern.cc (vern.cc/~foo redirects to foo.vern.cc). User sites for Gemini render on both foo.vern.cc and vern.cc/~foo with no redirection.
+User sites for HTTP are rendered on the URL foo.vern.cc and vern.cc/~foo. User sites for Gemini also render on both URLs
If you would like a service to be hosted by us, contact an admin and discuss it with them. You could also add it here. We are always open to new services to host, but it may take a while to get it fully set up.
