Finally, it's time to deploy. Choose MyToken contract in the contract dropdown and input the constructor argument. In this case, the argument will be the amount of the token you're creating. When you've done both these things, click deploy. You will get a metamask popup confirmation for the deploying transaction. Within no time (thanks to Zenith's fast block time), your contract will be deployed. You can interact with it within Remix in the Deployed Contracts section.
