Add a basic summary of how to build/install without Docker

Please. I run a server with nginx already hosting a bunch of stuff, so it would consume less resources if I just set it up that way.

Hello,

Sorry for late answer.

Is this page enough ?

https://github.com/webgiss/niolesk/blob/main/compilation.md

I'll also try to provide already compiled static page as binary for each release in a future versions.

Now releases are generated automatically with tags, and they contains as assets the compiled version of the niolesk web site. (As #19).

Thank you so much 😍 - Niolesk is really shining now. Especially the cached examples. Brilliant work.
