 This is diffing that understands HTML. Best suited for cases when you
 want to show a diff of user-generated HTML (like from a wysiwyg editor).
 
-##Usage
+## Usage (JavaScript)
 You use it like this:
 
 ```javascript
-
   diff = require('htmldiff.js');
   console.log(diff('<p>this is some text</p>', '<p>this is some more text</p>'));
 ```
+
 And you get:
 
 ```html
 <p>this is some <ins>more </ins>text</p>
 ```
-##Module
+
+## Usage (TypeScript)
+
+```typescript
+  import diff = require("htmldiff");
+  console.log(diff("<p>this is some text</p>", "<p>this is some more text</p>"));
+```
+
+`diff` is just an arbitry name for the exported default module function, you can use
+any other name you like, e. g.:
+
+```typescript
+  import diffHTML = require("htmldiff");
+  console.log(diffHTML("<p>this is some text</p>", "<p>this is some more text</p>"));
+```
+
+## Module
 
 It should be multi-module aware. ie. it should work as a node.js module
 or an AMD (RequireJS) module, or even just as a script tag.
