 With Embark you can:
 * Automatically deploy contracts and make them available in your JS code. Embark watches for changes, and if you update a contract, Embark will automatically redeploy the contracts (if needed) and the dapp.
+* Use any build pipeline or tool you wish, including grunt and meteor.
 * Do Test Driven Development with Contracts using Javascript.
 * Easily deploy to & use decentralized systems such as IPFS.
+* Keep track of deployed contracts, deploy only when truly needed.
 * Quickly create advanced DApps using multiple contracts.
 
 See the [Wiki](https://github.com/iurimatias/embark-framework/wiki) for more details.
