-- 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 ]]
-- ```
