You will also need to know, or find out, the IP address of your internet router and have a suitable static IP address for the Beaglebone on your local network. The router should allow you to forward ports to the Beaglebone (often this is under firewall or "advanced" settings).
You can either install from a debian package or manually as follows:
sudo apt-get install git
git clone https://github.com/bashrc/freedombone
cd freedombone
sudo make install
Plug the microSD card into your laptop/desktop and then run the *freedombone-prep* command. For example:
freedombone-prep -d /dev/sdX --ip <static LAN IP> --iprouter <router LAN IP>
