 # crypto-equality
 
-A Clojure library designed to ... well, that part is up to you.
+A very small Clojure library for protecting against
+[timing attacks][1] when comparing strings or sequences of bytes.
+
+[1]: https://en.wikipedia.org/wiki/Timing_attack
+
+## Installation
+
+Add the following dependency to your `project.clj` file:
+
+    [crypto-equality "0.1.0-SNAPSHOT"]
 
 ## Usage
 
-FIXME
+Require the `crypto.equality` namespace:
+
+```clojure
+(require '[crypto.equality :as crypto])
+```
+
+Then use the `eq?` function to compare strings, byte arrays, or any
+ordered sequence of integers.
+
+```clojure
+(crypto/eq? "foo" "foo") ;; => true
+(crypto/eq? "foo" "bar") ;; => false
+```
