+launching the language server on single files.
+
+Note: In order for neovim's built-in language server client to send the appropriate `languageId` to EFM, **you must
+specify `filetypes` in your call to `vim.lsp.config`**. Otherwise the server will be launch on the `BufEnter` instead
+of the `FileType` autocommand, and the `filetype` variable used to populate the `languageId` will not yet be set.
