 ## Why Use Zoe?
 
-### For Users
-
-**Zoe is safer.** Traditionally, putting digital assets in a smart
-contract has carried the risk of losing them. But Zoe guarantees you get either
-what you wanted or a full refund of the assets you put in. You will
-never leave a smart contract empty-handed, even if it is buggy or malicious.
-
-### For Developers
-
-**Zoe is easier.** Traditionally, writing a smart contract meant
-learning a new, untried language. And don't make any mistakes - if you
-do, your users might lose millions.
-
-However, you write Zoe contracts in a secure subset of JavaScript.
-Moreover, Zoe automatically escrows all user digital assets and
-handles their subsequent payout. **Even a buggy contract can't cause
-users to lose their assets.**
