[NTG-context] How to write a wiki page?

Hello All! I'd like to write a wiki page on special Fraktur fonts, but I don't know how to begin technically. Are there rules? Certanly, but where? To whom would I send the result to correct it with respect to format, ConTeXt commands, English language, bringing it into the ConTeXt wiki and so on? Greetings, Rudolf
