 Hardhat is a development environment for Ethereum software. It consists of different components for editing, compiling, debugging and deploying your smart contracts and dApps, all of which work together to create a complete development environment.
 
-# How to use hardhat on Fuse and Spark
+This Guide will walk you throught the steps on how to deploy an ERC-20 Token Contract to Fuse Blockchain using Hardhat.
 
-Following the instructions [here](https://hardhat.org/hardhat-runner/docs/getting-started#overview), run `npx hardhat` to create a hardhat project.
+## Pre-requisites
 
-Then in hardhat.config.js add Fuse and Spark to the network section:
+- Solidity programming knowledge
+- JavaScript knowledge
+
+Open a new terminal and run these commands to create a new folder:
+
+```bash
+mkdir hardhat-fuse-guide && cd hardhat-fuse-guide
+```
+
+Inside the folder, initialize a project by running
+
+```bash
+npm init -y
+```
+
+In the same directory where you installed Hardhat run:
+
+```bash
+npx hardhat init
+```
+
+Follow the prompts. A `package.json` file is added to the project dir, and we can then install Hardhat by running:
+
+Note:
+
+**Do you want to install this sample project's dependencies with npm (hardhat @nomicfoundation/hardhat-toolbox)? (Y/n) › y **
+
+```bash
+npm install --save-dev hardhat
+```
+
+Next install the Hardhat toolbox. The `@nomicfoundation/hardhat-toolbox` plugin bundles all the commonly used packages and Hardhat plugins to start developing with Hardhat.
+
+```bash
+npm install --save-dev @nomicfoundation/hardhat-toolbox
+```
+
+If you are using VS Code Editor, you can add the folder and look at the contents. In this guide, we will focus on the `hardhat.config.js` file, `Contracts` and `Scripts` directories. Open the Contract folder, delete the default `Lock.sol` file and add a new file `Token.sol`. Update the contents of `Token.sol` with the following code:
+
+```solidity
+// SPDX-License-Identifier: MIT
+pragma solidity ^0.8.0;
+
+import "@openzeppelin/contracts@4.0.0/token/ERC20/ERC20.sol";
+import "@openzeppelin/contracts@4.0.0/token/ERC20/extensions/ERC20Burnable.sol";
+import "@openzeppelin/contracts@4.0.0/access/Ownable.sol";
+
+contract MyToken is ERC20, ERC20Burnable, Ownable {
+    constructor(address initialOwner)
+        ERC20("MyToken", "MTK")
+        Ownable()
+    {}
+
+    function mint(address to, uint256 amount) public onlyOwner {
+        _mint(to, amount);
+    }
+}
+```
+
+To compile your contracts run:
+
+```bash
+$ npx hardhat compile
+```
+
+It will return the response:
+
+```bash
+Compiling...
+Compiled 1 contract successfully
+```
+
+The compiled artifacts will be saved in the artifacts/ directory by default. If you need to customize the Solidity compiler options, then you can do so through the solidity field in your hardhat.config.js
+
+The next step is to deploy the contracts to the Fuse Blockchain. Open the `Scripts` directory and update the contents of `deploy.js`
+
+```javascript
+const hre = require("hardhat");
+
+async function main() {
+  const token = await hre.ethers.deployContract("Token");
+
+  await token.waitForDeployment();
+
+  console.log(`Contract deployed to ${token.target}`);
+}
+
+main().catch((error) => {
+  console.error(error);
+  process.exitCode = 1;
+});
+```
+
+## Deploy Contract
+
+Open the `hardhat.config.js` file and update the information on Fuse Network
 
 ```typescript title="hardhat.config.js" overflow="wrap"
 module.exports = {
   // ...
   networks: {
     fuse: {
-      url: 'https://rpc.fuse.io/',

-}
+};
