+Natural Compare – [![Build][]][1] [![Coverage][]][2]
+===============
+
+Compare strings containing a mix of letters and numbers
+in the way a human being would in sort order.
+This is described as a "natural ordering".
+
+```text
+Standard sorting:   Natural order sorting:
+    img1.png            img1.png
+    img10.png           img2.png
+    img12.png           img10.png
+    img2.png            img12.png
+```
+
+String.naturalCompare returns a number indicating
+whether a reference string comes before or after or is the same
+as the given string in sort order.
+Use it with builtin sort() function.
+
+
+
+### Installation
+
+- In browser
+
+```html
+<script src=min.natural-compare.js></script>
+```
+
+- In node.js: `npm install natural-compare-lite`
+
+```javascript
+require("natural-compare-lite")
+```
+
+### Usage
+
+```javascript
+// Simple case sensitive example
+var a = ["z1.doc", "z10.doc", "z17.doc", "z2.doc", "z23.doc", "z3.doc"];
+a.sort(String.naturalCompare);
+// ["z1.doc", "z2.doc", "z3.doc", "z10.doc", "z17.doc", "z23.doc"]
+
+// Use wrapper function for case insensitivity
+a.sort(function(a, b){
+  return String.naturalCompare(a.toLowerCase(), b.toLowerCase());
+})
+
+// In most cases we want to sort an array of objects
+var a = [ {"street":"350 5th Ave", "room":"A-1021"}
+        , {"street":"350 5th Ave", "room":"A-21046-b"} ];
+
+// sort by street, then by room
+a.sort(function(a, b){
+  return String.naturalCompare(a.street, b.street) || String.naturalCompare(a.room, b.room);
+})
+
+// When text transformation is needed (eg toLowerCase()),
+// it is best for performance to keep
+// transformed key in that object.
+// There are no need to do text transformation
+// on each comparision when sorting.
+var a = [ {"make":"Audi", "model":"A6"}
+        , {"make":"Kia",  "model":"Rio"} ];
+
+// sort by make, then by model
+a.map(function(car){
+  car.sort_key = (car.make + " " + car.model).toLowerCase();
+})
+a.sort(function(a, b){
+  return String.naturalCompare(a.sort_key, b.sort_key);
+})
+```
+
+- Works well with dates in ISO format eg "Rev 2012-07-26.doc".
+
+
+### Custom alphabet
+
+It is possible to configure a custom alphabet
+to achieve a desired order.
+
+```javascript
+// Estonian alphabet
+String.alphabet = "ABDEFGHIJKLMNOPRSŠZŽTUVÕÄÖÜXYabdefghijklmnoprsšzžtuvõäöüxy"
+["t", "z", "x", "õ"].sort(String.naturalCompare)
+// ["z", "t", "õ", "x"]
+
+// Russian alphabet
+String.alphabet = "АБВГДЕЁЖЗИЙКЛМНОПРСТУФХЦЧШЩЪЫЬЭЮЯабвгдеёжзийклмнопрстуфхцчшщъыьэюя"
+["Ё", "А", "Б"].sort(String.naturalCompare)
+// ["А", "Б", "Ё"]
+```
