For example, to use `ruff-lsp` with Neovim, install `ruff-lsp` from PyPI along with
[`nvim-lspconfig`](https://github.com/neovim/nvim-lspconfig). Then, add something like the following
to your `init.lua`:
[`nvim-lspconfig`](https://github.com/neovim/nvim-lspconfig). Then, set up the Neovim LSP client
using the [suggested configuration](https://github.com/neovim/nvim-lspconfig/tree/master#configuration)
(`:h lspconfig-keybindings`). Finally, configure `ruff-lsp` in your `init.lua`:
