+
+### Running this project
+
+#### Gitpod
+
+To deploy this project to Gitpod, follow these steps:
+
+1. Click this link to deploy
+
+[![Open in Gitpod](https://gitpod.io/button/open-in-gitpod.svg)](https://gitpod.io/#github.com/dabit3/polygon-ethereum-nextjs-marketplace)
+
+2. In __pages/index.js__, pass in the RPC address given to you by GitPod to the call to `JsonRpcProvider` function:
+
+```javascript
+/* update this: */
+const provider = new ethers.providers.JsonRpcProvider()
+
+/* to this: */
+const provider = new ethers.providers.JsonRpcProvider("https://8545-youendpoint.gitpod.io/")
+```
+
+3. Import the RPC address given to you by GitPod into your MetaMask wallet

+
+#### Local setup
+
+To run this project locally, follow these steps.
+
+1. Clone the project locally, change into the directory, and install the dependencies:
+
+```sh
+git clone https://github.com/dabit3/polygon-ethereum-nextjs-marketplace.git
+
+cd polygon-ethereum-nextjs-marketplace
+
+# install using NPM or Yarn
+npm install
+
+# or
+
+yarn
+```
+
+2. Start the local Hardhat node
+
+```sh
+npx hardhat node
+```
+
+3. With the network running, deploy the contracts to the local network in a separate terminal window
+
+```sh
+npx hardhat run scripts/deploy.js --network localhost
+```
+
+4. Start the app
+
+```
+npm run dev
+```
+
+### Configuration
+
+To deploy to Polygon test or main networks, update the configurations located in __hardhat.config.js__ to use a private key and, optionally, deploy to a private RPC like Infura.
+
+```javascript
+require("@nomiclabs/hardhat-waffle");
+const fs = require('fs');
+const privateKey = fs.readFileSync(".secret").toString().trim() || "01234567890123456789";
+
+// infuraId is optional if you are using Infura RPC
+const infuraId = fs.readFileSync(".infuraid").toString().trim() || "";
+
+module.exports = {
+  defaultNetwork: "hardhat",
+  networks: {
+    hardhat: {
+      chainId: 1337
+    },
+    mumbai: {
+      // Infura
+      // url: `https://polygon-mumbai.infura.io/v3/${infuraId}`
+      url: "https://rpc-mumbai.matic.today",
+      accounts: [privateKey]
+    },
+    matic: {
+      // Infura
+      // url: `https://polygon-mainnet.infura.io/v3/${infuraId}`,
+      url: "https://rpc-mainnet.maticvigil.com",
+      accounts: [privateKey]
+    }
+  },
+  solidity: {
+    version: "0.8.4",
+    settings: {
+      optimizer: {
+        enabled: true,
+        runs: 200
+      }
+    }
+  }
+};
+```
+
+If using Infura, update __.infuraid__ with your [Infura](https://infura.io/) project ID.
