The Users Manual is produced by the MX Linux Community in American Standard English. It can be converted to another language using the Google Translate pull-down menu, which provides a basic translation which, though useful, is often difficult to understand.
Community members are working on correcting these machine translations (THANKS!), beginning with Sections 1 (Introduction) and 3 (Configuration). This page keeps track of the completed Sections by language.
