Suggestion for docs

[sinauq]

What version of Emacs are you running?

29.1

What version of LanguageTool are you running?

remote server

What version of this package are you running?

1.3

What is the current behaviour?

The document is not clear about how to use languagetool's premium server.

What is you expect to happen?

For anyone who might face the same problem, the config should be something like this:

(use-package languagetool
  :config
  (setq
   languagetool-server-url "https://api.languagetoolplus.com"
   languagetool-server-port 443
   languagetool-api-key "XXXX"
   languagetool-username "XXX"
   ))

Hi, I'm sorry you are experiencing this. Right now I do not have any way to test against premium LT, that's the main reason why the docs are so poor.

If you wanna help me improving the docs, I would appreciate it.

The only info referring to LT Plus are these lines in the ReadMe

languagetool.el/ReadMe.org

Lines 141 to 147 in b136d53

	If you pay for [[https://languagetool.org/proofreading-api][LanguageTool Proofreading API]] features, you can add the keys for
	the LanguageTool API as follows:
	#+BEGIN_SRC elisp
	(setq languagetool-api-key "xxxxxxxxxxxx"
	languagetool-username "[email protected]")
	#+END_SRC
