+How to install

+```
+
+To enable custom classes support you have to do this in project.xml
+
+```xml
+<define name="CUSTOM_CLASSES" />
+```
+
+or set this in build.hxml
+
+```hxml
+-D CUSTOM_CLASSES
+```
+
+Current Custom Class Limitations :
+
+- For now, you can only override functions from the current class, not from the extended part, like you cant override update in FlxText because FlxText doesnt have a update function overriden.
+- You cannot create custom classes that extends a typed class (those ones that has `<T>`), this will be implemented in the future.
+
+-----------
 
 Parse and evalutate Haxe expressions.
 
@@ -64,26 +87,40 @@ You can use `parser.allowJSON` to allow JSON data.
 
 You can use `parser.allowTypes` to parse types for local vars, exceptions, function args and return types. Types are ignored by the interpreter.
 
+You can use `parser.allowMetadata` to parse metadata before expressions on in anonymous types. Metadata are ignored by the interpreter.
+
 You can use `new hscript.Macro(pos).convert(ast)` to convert an hscript AST to a Haxe macros one.
 
+You can use `hscript.Checker` in order to type check and even get completion, using `haxe -xml` output for type information.
+
 Limitations
 -----------
 
 Compared to Haxe, limitations are :
 
-- no type declarations (classes, enums, typedefs) : only expressions
 - `switch` construct is supported but not pattern matching (no variable capture, we use strict equality to compare `case` values and `switch` value)
 - only one variable declaration is allowed in `var`
 - the parser supports optional types for `var` and `function` if `allowTypes` is set, but the interpreter ignores them
 - you can enable per-expression position tracking by compiling with `-D hscriptPos`
+- you can parse some type declarations (import, class, typedef, etc.) with parseModule
 
 Install
 -------
 
 In order to install Haxe Script, use `haxelib install hscript` and compile your program with `-lib hscript`.
 
-There are only three files in hscript :
+These are the main required files in hscript :
 
   - `hscript.Expr` : contains enums declarations
   - `hscript.Parser` : a small parser that turns a string into an expression structure (AST)
   - `hscript.Interp` : a small interpreter that execute the AST and returns the latest evaluated value
+
+Some other optional files :
+  
+  - `hscript.Async` : converts Expr into asynchronous version
+  - `hscript.Bytes` : Expr serializer/unserializer
+  - `hscript.Checker` : type checking and completion for hscript Expr
+  - `hscript.Macro` : convert Haxe macro into hscript Expr
+  - `hscript.Printer` : convert hscript Expr to String
+  - `hscript.Tools` : utility functions (map/iter)

+
+  - Enum matching with arguments for switch statements (for real and scripted enums)
+- Property Fields (`(get, set)` variables)
+
+  ```haxe
+  public var myvar(get, set):Int;
+  var _myvar:Int = 10;
+
+  function get_myvar():Int {
+    return _myvar;
+  }
+
+  function set_myvar(val:Int):Int {
+    if(val > 10) return _myvar = val;
+    return val;
+  }
+  ```
+
+  - `@:isVar` metadata support
+  
+- Static extension (`using`)
+
+  ```haxe
+  using StringTools;
+
+  class IntExtender {
+    static public function triple(i:Int) {
+      return i * 3;
+    }
+  }
+
+  // need to create/import the custom class
+  // before setting the extension (limitation for now)
+  using IntExtender;
+
+  var str = "  Hello World!  ";
+  trace(str.trim()); // "Hello World!"
+  trace(12.triple()); // 36
+  ```
+
+  - Support for real and custom classes
+- Misc.
+  - Allow using type parameters for creating objects (i.e. `var a = new TypedObject<Int>();`)
+  - Allow `package` declaration. Ignored by the interpreter.

+		Convert a script into asynchronous one.
+		- calls such as foo(a,b,c) are translated to a_foo(function(r) ...rest, a,b,c) where r is the result value
+		- object access such obj.bar(a,b,c) are translated to obj.a_bar(function(r) ...rest, a, b, c)
+		- @async expr will execute the expression but continue without waiting for it to finish
+		- @split [ e1, e2, e3 ] is transformed to split(function(_) ...rest, [e1, e2, e3]) which
+		  should execute asynchronously all expressions - until they return - before continuing the execution
+		- for(i in v) block; loops are translated to the following:
+			var _i = makeIterator(v);
+			function _loop() {
+				if( !_i.hasNext() ) return;
+				var v = _i.next();
+				block(function(_) _loop());
+			}
+			_loop()
+		- while loops are translated similar to for loops
+		- break and continue are correctly handled
+		- you can use @sync <expr> to disable async transformation in some code parts (for performance reason)
+		- a few expressions are still not supported (complex calls, try/catch, and a few others)
+
+		In these examples ...rest represents the continuation of execution of the script after the expression
