ARDUINO + ETHERNETE SHIEL 5100 + SENSOR LDR, I want an example of how to read my analog data and see them in blynk

Hi, I’m new to arduino and I think it’s great blynk, I have difficulties, I want to receive information from my LDR light sensor, I currently use an ethernet shield and a mega argon, LDR light sensor, rsistance. I’m using the blynk example program, then I do not know how to put the blynk language into arduino, some reference.
