I failed to setup LSP...

[Kakadu]

I tried to configure nvim from https://github.com/nvim-lua/kickstart.nvim for a first time, but got issues with applying your repo using a README. Instructions say, that I should use Plug ... and provide a command for non-neo vim. Maybe we should add a specific snippet for Lua to enable it? I found something, it doesn't complain immediately but I'm not sure.

Also, I stuck with enabling ocaml-lsp-server from my local opam PATH. Google says, that Mason is bad for this and I have troubles to enable OCaml-lsp in any manner.

This is what I have so far:
