Deploy HRC20

This section describes how to deploy a HRC20 smart contract on Harmony in 1-minute.

Overview
This section is designed to get the casual smart contract developer deploying HRC20 tokens (Harmony's ERC20 equivalent) on Harmony Network. This can be done in under one Minute.
This github repository contains the code and files used on this demo. You can also find many more examples that use HRC20 tokens on this github repository.
One Minute Deployment
Here is a short video running through the deployment:
One Minute Instructions
npm install -g [email protected]
git clone https://github.com/harmony-one/H20.git
cd H20
cp .envSample .env
npm install
truffle compile
truffle migrate --network testnet --reset
truffle networks
Interacting with Contracts
truffle console --network testnet
truffle(testnet)> HarmonyERC20.deployed().then(function(instance){myHRC20=instance})
undefined
truffle(testnet)> myHRC20.symbol()
'H20'
truffle(testnet)> myHRC20.name()
'HarmonyERC20'
truffle(testnet)> myHRC20.decimals()
BN { negative: 0, words: [ 18, <1 empty item> ], length: 1, red: null }
truffle(testnet)> myHRC20.totalSupply()
BN {
  negative: 0,
  words: [ 16777216, 62077800, 20718012, 3, <1 empty item> ],
