Well, there are two main methods of package management in FreeBSD, which (according to people who seem to know their stuff) should not be mixed.

Packages are pre-compiled binaries, which are installed with either:

• # pkg install <package>

  or

• $ doas pkg install <package>

and can be found at FreshPorts.

Then there are ports. You have to enable this during installation. Essentially, it gives you a directory containing all of the available sources, known as the ports tree. You cd in and run the command, and it pulls in the code, compiles it, and installs. However, due to my ancient processor, I do not use ports and so have no idea what commands to actually run or even where to find the ports tree in the first place.

Remember to check the documentation!
