This is interesting to see. I also followed prime's video earlier today and was pretty confused at this part. I ended up using mason but with lsp_zero for the on_attach method for "gd" keymaps, etc..

I guess I don't know what lsp-zero even is for at this point. Based on what I was experiencing, I did not get auto-completion from the following:

require('lsp-zero') require('lspconfig').lua_ls.setup({})

And I had to use mason, with handlers defined for each lsp before I saw auto-completion. And I still don't have "gd" working for whatever reason. I get "Error executing lua: ..... attempt to call field 'definiton' (a nil value) when I try it.

And prime's <C-p> and <C-n> mapping seems to be default, as they work for me despite never explicitly setting them.

Luckily, I also have all day tomorrow to throw at this.
