 Hyperactiv is a super small (< 1kb minzipped) library which **observes** object mutations and **computes** functions depending on those changes.
 
-In other terms, whenever an *observed object property* is **mutated**, the *computed functions* that **depend** on this property will be **called**.
+In other terms whenever a property from an observed object is **mutated**, every function that **depend** on this property are **called** right away.
 
-Of course, Hyperactiv **automatically** handles these dependencies so you **never** have to explicitly declare which *computed function* depends on which *observed property*.
