Development Setup

1. Install node, and npm on your computer which is required for running this project.
2. Install the dependencies for our project by running npm install
3. Ensure you have ganache installed and running on your machine. This is necessary to run the test blockchain network on your computer.
   • npm i -g ganache
4. Start the RPC server using ganache: ganache -p 7545
5. Ensure you have truffle installed using npm i -g truffle
6. Migrate our marketplace smart contract by running truffle migrate --reset inside the project directory.
7. Install MetaMask extension on a compatible web browser.
8. Add the local ganache network manually by opening MetaMask extension settings. Usual configuration would be:
   1. Name it anything that you wish
   2. RPC URL : http://localhost:7545
   3. Chain ID : copy from the ganache CLI output.
   4. Currency symbol : ETH
9. From ganache's CLI output, copy one of the private keys and import it into the MetaMask extension.
10. Run npm start within the project directory to start our web application.
11. Open http://localhost:3000 and start playing around with the marketplace by adding products and buying them!
    • Note that you have to switch to a different account by importing a different private key into the extension, before you can buy someone else's product.
