+### [bacon-ls](https://github.com/crisidev/bacon-ls) (Rust)
+
+The `bacon` command is required. If not exists, it will be installed globally.
+
+`bacon-ls` is not a replacement for `rust-analyzer`, they can be used together. The workspace folders feature is required. Therefore, the following configuration is necessary:
+```vim
+let g:lsp_experimental_workspace_folders = 1
+let g:lsp_settings_filetype_rust = ['rust-analyzer', 'bacon-ls']
+let g:lsp_settings = {
+\ 'rust-analyzer': {
+\   'initialization_options': {
+\     'checkOnSave': v:false,
+\     'diagnostics': v:false,
+\   },
+\}
+```
+
+For detailed configuration options, please refer to the [`bacon-ls` configuration documentation](https://github.com/crisidev/bacon-ls/blob/main/README.md#configuration).
+
 ### deno (TypeScript)
 
 To use deno, `deno.json(c)` should located on the project directory or traversing the filesystem upwards.
