 ## Why Nippy?
 
-- Small, simple **all-Clojure** library
+- Small, simple **pure-Clojure** library
 - **Terrific performance**: the [best](#performance) for Clojure that I'm aware of
 - Comprehensive support for [all standard data types](../../wiki/1-Getting-started#deserializing)
 - Easily extendable to [custom data types](../../wiki/1-Getting-started#custom-types)
-- **Robust test suite**, incl. full coverage for every supported type
-- Auto fallback to [Java Serializable](https://taoensso.github.io/nippy/taoensso.nippy.html#var-*freeze-serializable-allowlist*) when available
-- Auto fallback to Clojure Reader for all other types (including tagged literals)
-- Pluggable **compression** with built-in [LZ4](https://code.google.com/p/lz4/), [Zstandard](https://facebook.github.io/zstd/), etc.
-- Pluggable [encryption](../../wiki/1-Getting-started#encryption) with built-in AES128
+- **Robust test suite** incl. coverage of every supported type
+- **Mature** and widely used in production for 12+ years
+- Optional auto fallback to [Java Serializable](https://taoensso.github.io/nippy/taoensso.nippy.html#var-*freeze-serializable-allowlist*) for [safe](https://cljdoc.org/d/com.taoensso/nippy/CURRENT/api/taoensso.nippy#*freeze-serializable-allowlist*) types
+- Optional auto fallback to Clojure Reader (including tagged literals)
+- Optional smart **compression** with [LZ4](https://code.google.com/p/lz4/) or [Zstandard](https://facebook.github.io/zstd/)
+- Optional [encryption](../../wiki/1-Getting-started#encryption) with AES128
 - [Tools](https://taoensso.github.io/nippy/taoensso.nippy.tools.html) for easy + robust **integration into 3rd-party libraries**, etc.
 - Powerful [thaw transducer](https://taoensso.github.io/nippy/taoensso.nippy.html#var-*thaw-xform*) for flexible data inspection and transformation
 
+## Quick example
+
+Nippy's super easy to use:
+
+```clojure
+(require '[taoensso.nippy :as nippy])
+
+;; Freeze any Clojure value
+(nippy/freeze <my-value>) ; => Serialized byte[]
+
+;; Thaw the byte[] to get back the original value:
+(nippy/thaw (nippy/freeze <my-value>)) ; => <my-value>
+```
+
