+Installing foundryup...
+
+Detected your preferred shell is zsh and added foundryup to PATH.
+Run 'source /Users/qiaopengjun/.zshenv' or start a new terminal session to use foundryup.
+Then, simply run 'foundryup' to install Foundry.

+## Deployment steps
+
+1. 部署 `ERC20` 合约
+2. 部署 `ERC721` 合约
+3. 使用`ERC20` 合约地址作为初始化参数部署 `NFTMarket` 合约
+4. 账户1 在 `ERC20` 合约上 mint token
+5. 账户1 在 `ERC721` 合约上 safeMint NFT
+6. 账户1 在 `ERC721` 合约上调用 `setApprovalForAll` 授权 `NFTMarket` 合约，参数为 `NFTMarket` 合约地址和 `true`
+7. 账户1 在 `NFTMarket` 合约上调用 `listNFT` 挂单（上架 tokenId 为 0 的 NFT）
+8. 账户1 在 `ERC20` 合约上调用 `transfer` 转移 10个 ERC20 token 给 账户2
+9. 账户2 在 `ERC20` 合约上调用 `approve` 方法授权 `NFTMarket` 合约使用1个ERC20token，参数为 `NFTMarket` 合约地址 和数量 1,000,000,000,000,000,000
+10. 账户2 在 `NFTMarket` 合约上调用 `buyNFT` 购买 tokenId 为 0 的 NFT
+11. 查看账户1 和账户2 的 ERC20 和 ERC721 余额 （`balanceOf`）
