 A fast, safe, and intuitive DataFrame library.
 
-## Why use Haskell?
+## Why use this DataFrame library?
 
-* Having types around eliminates many kinds of bugs before you even run the code.
-* A highly composable programming model that makes it easy to write pipelines.
-* The Haskell compiler does a lot of optimization that makes code very fast.
-* The syntax is more approachable than other compiled languages' dataframes.
+* Encourages concise, declarative, and composable data pipelines through a powerful abstraction model.
+* Static typing makes code easier to reason about and catches many bugs at compile time—before your code ever runs.
+* Delivers high performance thanks to Haskell’s optimizing compiler and efficient memory model.
+* Designed for interactivity: expressive syntax, helpful error messages, and sensible defaults.
