On FreeBSD, Xorg can be installed as a package or port.
The binary package can be installed quickly but with fewer options for customization:
pkg install xorg
To build and install from the Ports Collection:
make install clean
Either of these installations results in the complete Xorg system being installed. Binary packages are the best option for most users.
A smaller version of the X system suitable for experienced users is available in x11/xorg-minimal. Most of the documents, libraries, and applications will not be installed. Some applications require these additional components to function.
