No installation instructions

I tried installing this plugin with vim-plugged as usual, but it didn't activate.

Plug 'LiadOz/nvim-dap-repl-highlights'

I tried doing it manually with

:lua require('nvim-dap-repl-highlights').setup()

But I got

E5108: Error executing lua [string ":lua"]:1: module 'nvim-dap-repl-highlights' not found:
        no field package.preload['nvim-dap-repl-highlights']
        no file './nvim-dap-repl-highlights.lua'

So I looked into the repository and saw the cargo file (rust is not mentioned as a dependency). So I built it with

cargo build --release --all-features

and amended my vimrc/init

Plug 'LiadOz/nvim-dap-repl-highlights' {'do': 'cargo build --release --all-features'}

I tried again, and again it didn't work (same error as above). I don't want to run a system wide install.

Please add documentation on how to install this.

I also noticed that the directory that I used to set up vim-plugged doesn't appear in that list of error messages. It should be in ~/.vim/plugged. All my other plugins work just fine like that.
