+--- LTeX Language Server: LSP language server for LanguageTool 🔍✔️ with support for LaTeX 🎓, Markdown 📝, and others
+---
+--- To install, download the latest [release](https://github.com/valentjn/ltex-ls/releases) and ensure `ltex-ls` is on your path.
+---
+--- This server accepts configuration via the `settings` key.
+---
+--- ```lua
+---   settings = {
+--- 		ltex = {
+--- 			language = "en-GB",
+--- 		},
+--- 	},
+--- ```
+---
+--- To support org files or R sweave, users can define a custom filetype autocommand (or use a plugin which defines these filetypes):
+---
+--- ```lua
+--- vim.cmd [[ autocmd BufRead,BufNewFile *.org set filetype=org ]]
+--- ```
