+rls, a language server for Rust
+
+See https://github.com/rust-lang/rls#setup to setup rls itself.
+See https://github.com/rust-lang/rls#configuration for rls-specific settings.
+All settings listed on the rls configuration section of the readme
+must be set under settings.rust as follows:
+
+```lua
+nvim_lsp.rls.setup {
+  settings = {
+    rust = {
+      unstable_features = true,
+      build_on_save = false,
+      all_features = true,
+    },
+  },
+}
+```
+
+If you want to use rls for a particular build, eg nightly, set cmd as follows:
+
+```lua
+cmd = {"rustup", "run", "nightly", "rls"}
+```
+    ]],
