-To properly use Typst, you should also install the fonts "Linux Libertine" and
-"New Computer Modern Math". They are available as part of this repository in
-`assets/fonts` or you can install them through the package manager of your
-choice.
-
 You can also watch source files and automatically recompile on changes. This is
 faster than compiling from scratch each time because Typst has incremental
 compilation.
