• git clone https://github.com/mycoralhealth/blockchain-tutorial.git
• navigate to this directory and rename the example file mv example.env .env
• go run main.go
• open a web browser and visit http://localhost:8080/
• to write new blocks, send a POST request (I like to use Postman) to http://localhost:8080/ with a JSON payload with BPM as the key and an integer as the value. For example:

{"BPM":50}

• Send as many requests as you like and refresh your browser to see your blocks grow! Use your actual heart rate (Beats Per Minute) to track it over time.
