+
+[LIVE DEMO](http://classic.scrypt.io/voting/) 🚀
+
+## Step 1. Clone the project
+
+```bash
+$ git clone https://github.com/sCrypt-Inc/voting.git
+```
+
+## Step 2. Install dependencies
+
+```bash

+
+## Step 3. Compile contract
+
+```bash
+$ npx scrypt-cli compile
+```
+
+ ## Step 4. Deploy contract
+
+Before deploying the contract, create a `.env` file and save your private key in the `PRIVATE_KEY` environment variable.
+
+```text
+PRIVATE_KEY=xxxxx
 ```
-npm run compile
-npm run deploycontract
+
+If you don't have a private key, please follow [this guide](https://scrypt.io/docs/how-to-deploy-and-call-a-contract/#setup) to generate one using [Sensilet](https://sensilet.com/) wallet, then fund the private key's address with our [faucet](https://scrypt.io/faucet/).
+
+Run the following command to deploy the contract.
+
+```bash
+$ npm run deploy:contract
 ```
 
-### `npm start`
+After success, you will see an output similar to the following:
