1.) Clone repo locally
2.) cd cmd
3.) go build
4.) There are several ways to execute the program.
4a.) To generate a checksum for an event without a binary value, simply call `./cmd`.
4b.) To generate a checksum for an event with a binary value, call `./cmd -b`
4c.) To generate an event with a binary value and POST it to a local instance of EdgeXFoundry, call `./cmd -b -p`
5.) Do it repeatedly and you should see that the checksum is different each time.
