## 安裝指令

* yarn install truffle
* npm install -g truffle
* truffle init--->
==ex:產生 ./contracts/1_initial_migration.js. ./contracts/2_crypto_zombies.js==
* npm install truffle-hdwallet-provider
* truffle compile---> compile ABI (compile smart contracts' byte code)--->產生build artifacts 存在./build 目錄內

* 程式碼驗證--->

var Migrations = artifacts.require("./Migrations.sol");
module.exports = function(deployer) {//contract 名稱為migrations.sol 可更改
  deployer.deploy(Migrations);
};

truffle-config.js
* 設定好smart contract 要 migrate 的 network(testnet/mainnet(poa)--->mainnet又可以分tokenaddress mainnet/mianet--->多種各自==rpc不同==的mainnet)
