+---
+--- nelua-lsp is an experimental nelua language server.
+---
+--- You need [nelua.vim](https://github.com/stefanos82/nelua.vim/blob/main/ftdetect/nelua.vim) for nelua files to be recognized or add this to your config:
+---
+--- in vimscript:
+--- ```vimscript
+--- au BufNewFile,BufRead *.nelua setf nelua
+--- ```
+---
+--- in lua:
+--- ```lua
+--- vim.api.nvim_create_autocmd({ "BufNewFile", "BufRead" }, { pattern = { "*.nelua" }, command = "setf nelua"})
+--- ```
+---
+--- **By default, nelua-lsp doesn't have a `cmd` set.** This is because nvim-lspconfig does not make assumptions about your path. You must add the following to your init.vim or init.lua to set `cmd` to the absolute path ($HOME and ~ are not expanded) of the unzipped run script or binary.
+---
+--- ```lua
+--- vim.lsp.config('nelua_lsp', {
+---     cmd = { "nelua", "-L", "/path/to/nelua-lsp/", "--script", "/path/to/nelua-lsp/nelua-lsp.lua" },
+--- })
+--- ```
+
+---@type vim.lsp.Config
+return {
+  filetypes = { 'nelua' },
+  root_markers = { 'Makefile', '.git', '*.nelua' },
+}
