 #### Description
 
-Initializes the ethernet library and network settings.
+Initializes the Ethernet library and network settings.
 
 With version 1.0, the library supports DHCP. Using Ethernet.begin(mac) with the proper network setup, the Ethernet shield will automatically obtain an IP address. This increases the sketch size significantly. To make sure the DHCP lease is properly renewed when needed, be sure to call Ethernet.maintain() regularly.
