 ### Notes:
 1. Use `#v(-spacing)` to remove vertical spacing between titles (this cannot be automatically handled by the template). Variable `spacing` used here is imported from the template.
 2. When importing `@local/nure:0.1.0` and specifying file paths in functions handled by the package, the path will relative to package's root directory, e.g. setting `#show: coursework.with(bib_path: "bibl.yml")` will evaluate to `~/.local/share/typst/packages/local/nure/0.1.0/bibl.yml`, the same is for `#img` function, which makes it quite annoying and forces one to import `lib.typ` file. Please open an issue or contact us in any other way if you have any advice.
