Is your feature request related to a problem? Please describe.

The problem is that there is no explanation on "where to place the setup() call"

Describe the solution you'd like

I personnaly added this in the ~/.config/nvim/init.vim:

lua require('mason').setup()

I know there are others possibilities.

What I mention is that there is nowhere in the README to explain where to add this call line. It could be a bit complicated for novice users or who don't know how to add lua calls :)

Describe potential alternatives you've considered
