+---
+--- A Language Server Protocol implementation for Ruff, an extremely fast Python linter and code formatter, written in Rust. It can be installed via `pip`.
+---
+--- ```sh
+--- pip install ruff
+--- ```
+---
+--- **Available in Ruff `v0.4.5` in beta and stabilized in Ruff `v0.5.3`.**
+---
+--- This is the new built-in language server written in Rust. It supports the same feature set as `ruff-lsp`, but with superior performance and no installation required. Note that the `ruff-lsp` server will continue to be maintained until further notice.
+---
+--- Server settings can be provided via:
+---
+--- ```lua
+--- vim.lsp.config('ruff', {
+---   init_options = {
+---     settings = {
+---       -- Server settings should go here
+---     }
+---   }
+--- })
+--- ```
+---
+--- Refer to the [documentation](https://docs.astral.sh/ruff/editors/) for more details.
