Installing ports upon FreeBSD install

I use DesktopBSD (FreeBSD + KDE) and regularly install this on our machines. Currently I go to the package manager to install the ports, but what shell command can I enter instead right after BSD install to install the ports?

Thanks in advance

There's an excellent article at the FreeBSD's handbook.

Excellent. And from this article I understand that the objective is called "obtaining the Ports Collection".

cvsup or portsnap to grab the latest ports tree, then its just a matter of "make install"
