+LTeX Language Server: LSP language server for LanguageTool 🔍✔️ with support for LaTeX 🎓, Markdown 📝, and others
+
+To install, download the latest [release](https://github.com/ltex-plus/ltex-ls-plus) and ensure `ltex-ls-plus` 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 ]]
+```
+]=],
+  },
+}
