Bare-Metal CV is a minimal (yet professional), beginner-friendly CV/resume template in ~100 lines of LaTeX
To use it, open main.tex (either copy/paste or download it) in your favorite LaTeX editor (if you don't have one, use overleaf)
No obscure LaTeX packages, just geometry, hyperref and enumitem (plus a the charter font).
No weird commands, configuration settings or hard to understand syntactic sugars.
Just a single file containing ~100 lines of simple, easy to understand LaTeX code.
