Using relm book offline?

[OleksiiGrinka]

Because I live in Ukraine I have some need to access relm book offline.
Yes I know that I can print it as pdf file but that not very convenient, I'm looking for something like rustup doc --book

Maybe this will help

mdbook serve

and open this link on browser: http://localhost:3000

Source: https://rust-lang.github.io/mdBook/guide/creating.html#initializing-a-book

I get this error:

~/P/y/book (main|✔) $ mdbook serve
 INFO Book building has started
 INFO Running the html backend
ERROR Rendering failed
	Caused by: Error rendering "index" line 177, col 29: Missing font github
	Caused by: Missing font github

Where I can get 'github' font? or maybe how can I replace it in book to other font that is present on my system

I ran with no issues.

➜ nix run nixpkgs#mdbook serve

Can you run it firstly with internet to download this fonts and then run it without internet

[OleksiiGrinka]

well I already ran it with internet, I git cloned book from main branch of https://github.com/Relm4/book

The version from git works for me with mdbook v0.5.2.
Maybe there were some recent commits that are important though, so a git pull might also help.

It actually works now after a git pull, thanks!
