First line of the readme says:

Configs for the Nvim LSP client (:help lsp).

We can expand on it:

nvim-lspconfig is a collection of configurations for use with the Nvim builtin LSP client, to save you the trouble of manually creating such configurations. For example to use Nvim LSP with a typescript project, you would need to

1. install the typescript language server
2. in your init.lua (or init.vim) configure it like this: https://github.com/neovim/nvim-lspconfig/blob/80fddd28de5fe0642da7adee955f5762b933e730/lua/lspconfig/server_configurations/tsserver.lua#L3-L26

With nvim-lspconfig, you only need to:

1. install the typescript language server
2. in your init.lua (or init.vim) call require'lspconfig'.tsserver.setup{}

Is that clear?
