# Introduction
GAMADV-XTD3 is a free, open source command line tool for Google Workspace Administrators to manage domain and user settings quickly and easily.

GAMADV-XTD3 is built with Python 3; as Python 2 support ends on 2020-01-01, this is the version of Advanced GAM that new/existing users should install.

This page provides simple instructions for downloading, installing and starting to use GAMADV-XTD3.

GAMADV-XTD3 requires paid, or Education/Non-profit, editions of Google Workspace. G Suite Legacy Free Edition has limited API support and not all GAM commands work.

GAMADV-XTD3 is a rewrite/extension of Jay Lee's [GAM], without his efforts, this version wouldn't exist.

GAMADV-XTD3 is backwards compatible with [GAM], meaning that if your command works with regular GAM, it will also work with GAMADV-XTD3. There may be differences in output, but the syntax is compatible.
