That example is much larger than what is required to get you up and running.
This is a much simpler dhcpd.conf that should get you started:
# Configuration file for dhcpd
# Configuration for the main range
subnet 192.168.1.0 netmask 255.255.255.0
range 192.168.1.100 192.168.1.200;
option subnet-mask 255.255.255.0;
option routers 192.168.1.1;
option domain-name-servers 22.214.171.124, 126.96.36.199;
option domain-name "home.com";
Change your IP range and DNS servers to fit your network, though that is the common IP range for a home network.
