+# Ascii Art Reverse
+
+This is package is essentially a rainbow being
+farted from the aft portion of a unicorn. It's pure magic.
+
+# Install
+
+`npm install ascii-art-reverse`
+
+# Usage
+
+```javascript
+var reverse = require('ascii-art-reverse');
+
+var art = 
+ "    ("-^-/")  " +
+ "    `o__o' ]  " +
+ "    (_Y_) _/  " +
+ "  _..`--'-.`, " +
+ " (__)_,--(__) " +
+ "     7:   ; 1 " +
+ "   _/,`-.-' : " +
+ "  (_,)-~~(_,) ";
+
+console.log(reverse(art));
+```
+
+### Output:
+
+```
+ ("\-^-")   
+ [ 'o__o`   
+ \_ (_Y_)   
+,`.-'--`.._ 
+(__)--,_(__)
+1 ;   :7    
+: '-.-`,\_  
+(,_)~~-(,_) 
+```
+
+Like I said, __MAGIC__.
