Answers:

Download the ESP8266 community boards as instructed in the video tutorial. Also, make the changes in the Tools option as shown in the video. If you are getting error as "does not exist or your board is not connected" then there must not be a proper connection between your laptop/PC and Arduino. Also, make sure you have connected Rx-Tx pins of Arduino and ESP module properly as instructed.
