+## HardHat2 部署
+### Node.js v16 安装
+HardHat2 需要 Node.js v16 及以上的版本
+这里给出的是通过 npm 来将旧版本升级到 Node.js v16 的，如果想要直接安装的话通过 `yum install nodejs` 或者 `apt install nodejs` 来即可。
+```bash
+npm config set registry https://registry.npmmirror.com
+sudo npm install -g n
+sudo n 16
+``` 
+安装完成之后可以查看版本，如果没有更新可以重新刷新一下环境（直接退出重连最简单）
+```bash
+node -v
+# v16.20.2
+npm -v
+# 6.14.15
+```
+### 安装 Hardhat2
+创建一个 hardhat2-project 目录，初始化 npm 项目，注意这里不要用 hardhat 作为项目名
+```bash
+mkdir ~/hardhat2-project
+cd ~/hardhat2-project
+npm init -y
+```
+安装 Hardhat 2
+```bash
+npm install --save-dev hardhat@^2.23.0
+```
+初始化 Hardhat2 项目
+```bash
+npx hardhat --init
+```
+选择
+```bash
+✔ What do you want to do? · Create a JavaScript project
+✔ Hardhat project root: · /root/hardhat2-project
+✔ Do you want to add a .gitignore? (Y/n) · y
+✔ Help us improve Hardhat with anonymous crash reports & basic usage data? (Y/n) · y
+✔ Do you want to install this sample project's dependencies with npm (@nomicfoundation/hardhat-toolbox)? (Y/n) · y
+```
+## 使用 Hardhat2 编译测试合约
+在 hardhat2-project 目录下，执行以下命令来编译合约
+合约都会放在 `contracts` 目录下，这里我们选择了一个默认的合约，因此可以直接编译
+```bash
+# 测试编译
+npx hardhat compile
+# 运行测试
+npx hardhat test
+# 查看可用任务
+npx hardhat help
+```
