+
+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
+```
+
+_Requires Ruff v0.3.3 or later._
+
+This is the new Rust-based version of the original `ruff-lsp` implementation. It's currently in alpha, meaning that some features are under development. Currently, the following capabilities are supported:
+
+1. Diagnostics
+2. Code actions
+3. Formatting
+4. Range Formatting
+
+Please note that the `ruff-lsp` server will continue to be maintained until further notice.
