# 8 On-Line Help

TNT includes online help in the form of this users guide and other documentation. The online help is displayed in a web browser. On Unix systems, TNT will attempt to run firefox, opera, mozilla, and netscape, in that order, to display the files. On Windows, TNT will attempt to launch the default web browser on the document.

Printable versions of these documents are also available in TNT's `doc` directory, in portable document format (PDF).
