+--- A Language Server Protocol server for OpenSCAD
+---
+--- You can build and install `openscad-language-server` binary with `cargo`:
+--- ```sh
+--- cargo install openscad-language-server
+--- ```
+---
+--- Vim does not have built-in syntax for the `openscad` filetype currently.
+---
+--- This can be added via an autocmd:
+---
+--- ```lua
+--- vim.cmd [[ autocmd BufRead,BufNewFile *.scad set filetype=openscad ]]
+--- ```
+---
+--- or by installing a filetype plugin such as https://github.com/sirtaj/vim-openscad
+
+---@type vim.lsp.Config
+return {
+  cmd = { 'openscad-language-server' },
+  filetypes = { 'openscad' },
+  root_markers = { '.git' },
