Finding Ports to Install in FreeBSD

FreeBSD is founded on the idea that compiling is faster/better than using pre-made packages. To make compiling easy FreeBSD uses a “package management” system called ports; however, it is difficult to find the port to compile since FreeBSD’s package management system is really just empty directories with build instructions.
