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.
Wow, I'm surprised that there is not a single post in here yet. Let's this to be the first one. I'm using NeoVIM tbh but we all know where we came from, right ?
