New language

Hi all!

How can I add new language to languagetool and make rules for it?

Hi, thanks for your interest in LanguageTool. As a first step, you can add your rules to an existing language, as described at Development Overview - LanguageTool Wiki. In other words, you simple add rules for the new language X to e.g. English. Of course you cannot use advanced features like part-of-speech tagging yet. Which language would you like to add?
