Something to add to the readme

[dadaurs]

I just installed pywal and wal.vim on my laptop and spent half an hour trying to figure out why it wasn’t working.

Turns out you cannot set

set termguicolors

in your vimrc or init.vim file.

I just thought it would be a good idea to mention this in the readme, since it is somewhat painful to figure out, and termguicolors is a pretty default setting as far as I know.
