 **Usage Example:** _Calculate the fee for a transaction._
 
-To figure out the complete transaction fee at this point just requires one more bit of math: determining out how much money is going through the .vout. That's a simple use of JQ where you just use `awk` to sum up the `value` of all the `vout` information:

 ```
-To complete the transaction fee calculation,, you subtract the .vout .amount (1.045) from the .vin .amount (1.3).
