+  U8glib Example Overview:
+    Frame Buffer Examples: clearBuffer/sendBuffer. Fast, but may not work with all Arduino boards because of RAM consumption
+    Page Buffer Examples: firstPage/nextPage. Less RAM usage, should work with all Arduino boards.
+    U8x8 Text Only Example: No RAM usage, direct communication with display controller. No graphics, 8x8 Text only.
+    
+  This is a page buffer example.
