+didYouMean.js - A simple JavaScript matching engine
+===================================================
+
+[Available on GitHub](https://github.com/dcporter/didyoumean.js).
+
+A super-simple, highly optimized JS library for matching human-quality input to a list of potential
+matches. You can use it to suggest a misspelled command-line utility option to a user, or to offer
+links to nearby valid URLs on your 404 page. (The examples below are taken from a personal project,
+my [HTML5 business card](http://dcporter.aws.af.cm/me), which uses didYouMean.js to suggest correct
+URLs from misspelled ones, such as [dcporter.aws.af.cm/me/instagarm](http://dcporter.aws.af.cm/me/instagarm).)
+Uses the [Levenshtein distance algorithm](https://en.wikipedia.org/wiki/Levenshtein_distance).
+
+didYouMean.js works in the browser as well as in node.js. To install it for use in node:
+
+```
+npm install didyoumean
+```
+
+
+Examples
+--------
+
+Matching against a list of strings:
+```
+var input = 'insargrm'
+var list = ['facebook', 'twitter', 'instagram', 'linkedin'];
+console.log(didYouMean(input, list));
+> 'instagram'
+// The method matches 'insargrm' to 'instagram'.
+
+input = 'google plus';
+console.log(didYouMean(input, list));
+> null
+// The method was unable to find 'google plus' in the list of options.
+```
+
+Matching against a list of objects:
+```
+var input = 'insargrm';
+var list = [ { id: 'facebook' }, { id: 'twitter' }, { id: 'instagram' }, { id: 'linkedin' } ];
+var key = 'id';
+console.log(didYouMean(input, list, key));
+> 'instagram'
+// The method returns the matching value.
+
+didYouMean.returnWinningObject = true;
+console.log(didYouMean(input, list, key));
+> { id: 'instagram' }
+// The method returns the matching object.
+```
+
+
+didYouMean(str, list, [key])
+----------------------------
+
+- str: The string input to match.
+- list: An array of strings or objects to match against.
+- key (OPTIONAL): If your list array contains objects, you must specify the key which contains the string
+  to match against.
+
+Returns: the closest matching string, or null if no strings exceed the threshold.
+
+
+Options
+-------
+
+Options are set on the didYouMean function object. You may change them at any time.
+
+### threshold
+
+  By default, the method will only return strings whose edit distance is less than 40% (0.4x) of their length.
+  For example, if a ten-letter string is five edits away from its nearest match, the method will return null.
+
+  You can control this by setting the "threshold" value on the didYouMean function. For example, to set the
+  edit distance threshold to 50% of the input string's length:
+
+  ```
+  didYouMean.threshold = 0.5;
+  ```
+
+  To return the nearest match no matter the threshold, set this value to null.
+
+### thresholdAbsolute
+
+  This option behaves the same as threshold, but instead takes an integer number of edit steps. For example,
+  if thresholdAbsolute is set to 20 (the default), then the method will only return strings whose edit distance
+  is less than 20. Both options apply.
+
+### caseSensitive
+
+  By default, the method will perform case-insensitive comparisons. If you wish to force case sensitivity, set
+  the "caseSensitive" value to true:
+
+  ```
+  didYouMean.caseSensitive = true;
+  ```
+
+### nullResultValue
+
+  By default, the method will return null if there is no sufficiently close match. You can change this value here.
+
+### returnWinningObject
+
+  By default, the method will return the winning string value (if any). If your list contains objects rather
+  than strings, you may set returnWinningObject to true.
+  
+  ```
+  didYouMean.returnWinningObject = true;
+  ```
+  
+  This option has no effect on lists of strings.
+
+### returnFirstMatch
+  
+  By default, the method will search all values and return the closest match. If you're simply looking for a "good-
+  enough" match, you can set your thresholds appropriately and set returnFirstMatch to true to substantially speed
+  things up.
