 How to install
 ```
-haxelib git hscript-improved https://github.com/FNF-CNE-Devs/hscript-improved.git
+haxelib git hscript-improved https://github.com/CodenameCrew/hscript-improved.git
 ```
 
 To enable custom classes support you have to do this in project.xml
+
 ```xml
 <define name="CUSTOM_CLASSES" />
 ```
-Warning: custom classes are sometimes broken, would like help to fix them. 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
+
+or set this in build.hxml
+
+```hxml
+-D CUSTOM_CLASSES
+```
+
+Current Custom Class Limitations :
+
+- You cannot create custom classes that extends a typed class (those ones that has `<T>`), this will be implemented in the future.

+# FEATURES
+
+- Custom Classes
+  - Final Classes
+  - Static Classes
+  - Allow for type check (`is`)
+  - Allow extending other custom classes
+- Enums
+
+  ```haxe
+  enum TypeValue {
+    NUMBER(n:Int);
+    DECIMAL(d:Float, ?p:Int);
+    CHARACTER(s:String);
+    BOOLEAN(b:Bool);
+  }
+
+  var type = TypeValue.DECIMAL(10.1234, 2);
+  // You need to type the full enum field for each case
+  // i.e. you can't type the enum field directly (limitation for now)
+  switch(type) {
+    case TypeValue.NUMBER(number): 
+      trace("number: " + number);
+    case TypeValue.DECIMAL(decimal, precision): 
+      if(precision != null)
+        trace("decimal: " + decimal + " | rounded decimal: " + roundDecimal(decimal, precision));
+      else
+        trace("decimal: " + decimal);
+    case TypeValue.CHARACTER(char): 
+      trace("character: " + char);
+    default: 
+      trace("unknown type");
+  }
+
+  function roundDecimal(Value:Float, Precision:Int) {
+    var mult:Float = Math.pow(10, Precision);
+    return Math.fround(Value * mult) / mult;
+  }
+  ```
+
+  - 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.
