-# Install it
+Installation
+------------
+
+This library is distributed with [npm](https://www.npmjs.com/package/php-parser) :
 
 ```sh
-$ npm install php-parser --save
+npm install php-parser --save
 ```
 
-# Use it
+Usage
+-----
 
 ```js
+// initialize the php parser factory class
+var engine = require('php-parser');
 // initialize a new parser instance
-var parser = require('php-parser').create();
-
-// how to retrieve the AST
+var parser = new engine({
+  // some options :
+  parser: {
+    extractDoc: true
+  },
+  ast: {
+    withPositions: true
+  }
+});
+
+// Retrieve the AST from the specified source
 var AST = parser.parseEval('echo "Hello World";');
+// AST.kind === 'program';
+// AST.children[0].kind === 'echo';
 
-// how to list tokens
+// Retrieve an array of tokens (same as php function token_get_all)
 var tokens = parser.tokenGetAll('<?php echo "Hello World";');
 ```
 
-For more details please [visit he wiki](https://github.com/glayzzle/php-parser/docs).

-# Output
+Sample AST output
+-----------------
 
 ```js
-[
-  'program',  <-- program node
-  [
-    [ 'sys',  <-- first child, typed system call
-      'echo', <-- operation echo
-      [
-        [ 'string', '"Hello World"' ]  <-- first argument
+{
+  'kind': 'program',
+  'children': [
+    {
+      'kind': 'echo',
+      'arguments': [

-# Contributing
+API Overview
+------------
 
-If you want to contribute please visit this repository https://github.com/glayzzle/php-parser-dev.
+The main API exposes a class with the following methods :
+
+- **parseEval**(String buffer) : parse a PHP code in eval style mode (without php open tags)
+- **parseCode**(String buffer, String filename) : parse a PHP code by using php open tags.
+- **tokenGetAll**(String buffer) : retrieves a list of all tokens from the specified input.
+
+You can also [pass options](https://github.com/glayzzle/php-parser/wiki/Options) that change the behavior of the parser/lexer.
+
