Circom language tutorial with circomlib walkthrough

This tutorial introduces the Circom language and how to use it, along with common pitfalls

Circom is a fantastic tool for learning zk-snarks. However, because it is quite low-level, there are more opportunities to accidentally add subtle bugs. In real applications, programmers should consider using higher level zero knowledge programming languages. You should always get an audit before deploying a smart contract that holds user funds, but this is especially true for zk circuits, as the attack vectors are less well known.
