How to use this languages server without coc, just via inbuilt lsp of nvim?

[s624]

Most people in the nvim community do not use nvim. Even if they do, it's always better to know how to configure this language server with the inbuilt lsp client of nvim.
Right now, I am trying. And I am also realizing that if a ducumentation was already present in the readme file or in the wiki section then that would have been immensely helpful.
