+JavaScript port of [HtmlDiff.NET](https://github.com/Rohland/htmldiff.net) which is itself a C# port of the Ruby implementation, [HtmlDiff](https://github.com/myobie/htmldiff/).
+
+Project Description
+-------------------
+
+Diffs two HTML blocks, and returns a meshing of the two that includes `<ins>` and `<del>` elements.  The classes of these elements are `ins.diffins` for new code, `del.diffdel` for removed code, and `del.diffmod` and `ins.diffmod` for sections of code that have been changed.
+
+For "special tags" (primarily style tags such as `<em>` and `<strong>`), `ins.mod` elements are inserted with the new styles.
+
+Further description can be found at this [blog post](http://www.rohland.co.za/index.php/2009/10/31/csharp-html-diff-algorithm/) written by Rohland, the author of HtmlDiff.NET.
+
+**Note**: The diffing algorithm isn't perfect.  One example is that if a new `<p>` ends in the same string as the previous `<p>` tag did, two `<ins>` tags will be created: one starting at the beginning of the common string in the first `<p>` and one in the second `<p>` containing all the content up to the point the trailing common string begins.  It's a little frustrating, but I didn't write the algorithm (and honestly don't really understand it); I only ported it.
+
+Usage
+-----
+
+#### Html ####
+
+```html
+<html>
+<body>
+    <div id="oldHtml">
+        <p>Some <em>old</em> html here</p>
+    </div>
+
+    <div id="newHtml">
+        <p>Some <b>new</b> html goes here</p>
+    </div>
+
+    <div id="htmlDiff">
+    </div>
+</body>
+</html>
+```
+
+#### JavaScript ####
+
+```javascript
+import HtmlDiff from 'htmldiff-js';
+
+
+let oldHtml = document.getById('oldHtml');
+let newHtml = document.getById('newHtml');
+let diffHtml = document.getById('diffHtml');
+
+diffHtml.innerHTML = HtmlDiff.execute(oldHtml.innerHTML, newHtml.innerHTML);
+```
+
+Demo
+----
+
+I didn't port the demo, but it should output markup the same way the [htmldiff.net demo](https://github.com/Rohland/htmldiff.net/tree/master/Demo) does with a slight exception in what appeared to me to be a bug, which I 'fixed'.  I can no longer remember what that bug was, as I only ported this project quickly in order to use it in another project.
