TJ made a nice video about how to start with neovim and its configuration. I hope that this link is not against the rules since it’s about neovim and not about vim … Personally I find those 2 very very alike and with the features that I need for my daily work, I can use either one of them without noticing any difference.

Enjoy !
Also, it’s a bit frustrating. That video is out of date as it’s prior to the conversion to lazy.nvim
You should rather than just dumping init.lua in place actually git clone the repo into your ~/.config directory. There are instructions for that in the README.
