 ## About
 
-Angel3 is a fork of archived Angel framework to support Dart SDK 2.12.x or later. It is a full-stack Web framework in Dart that aims to streamline development by providing many common features out-of-the-box in a consistent manner. One of the main goal is to enable developers to build both frontend and backend in the same language, Dart. Angel3 framework is designed as a collection of plugins that enable developers to pick and choose the parts needed for their projects. A series of starter templates are also provided for quick start and trial run with Angel3 framework. Visit our [website](<https://angel3-framework.web.app/>) to learn more.
+Angel3 started life as a fork of the archived `Angel framework` to support null-safety in Dart SDK 2.12.x and beyond. It is a full-stack Web framework in Dart that aims to streamline development by providing many common features out-of-the-box in a consistent manner. One of the main goal is to enable developers to build both frontend and backend in the same language, Dart. Angel3 framework is designed as a collection of plugins that enable developers to pick and choose the parts needed for their projects. A series of starter templates are also provided for quick start and trial run with Angel3 framework. Visit our [website](<https://angel3-framework.web.app/>) for more details.
 
 The available features in Angel3 includes:
 
-* Static File Handling
+* Basic and OAuth2 Authentication
-* Basic Authentication
+* ORM for PostgreSQL and MySQL
-* PostgreSQL ORM
+* MongoDB
 * GraphQL
-* And much more...
+* Proxy and Cache
+* Static File Handling
+* Server Side Rendering
+* Websocket
 
 See all the available [`packages`](https://angel3-docs.dukefirehawk.com/packages) for more information.
 
 ## Important Notes
 
-The core Angel Framework migration to Angel3 Framework has completed and published under `angel3_` prefix on pub.dev. The migrated packages have passed all the test cases. The development work will now move onto the next phase which is to refactor and to improve on the features for better development and deployment experience.
+The development work are currently focused on:
+
+* Keeping the packages with `angel3_` prefix in sync with Dart SDK releases
+  * Remove and replace deprecated classes and methods while keeping backward compatible
+  * Refactor the code to use new language features
+* Fix and resolve reported issues
+* Performance tunning
+* Improve on existing features, unit test, user guide and examples
+* Add new features
 
 The status of the code base is as follows:

-A better IoC container generator for Angel3, ultimately allowing Angel3 to be used without `dart:mirrors`.
+An alternative container for Angel3 that uses `reflectable` instead of `dart:mirrors` for reflection.
+
+## Usage
+
+* Annotable the class with `@contained`.
+* Run `dart run build_runner build <Your class directory>`
+* Alternatively create a `build.xml` file with the following content
+
+    ```yaml
+    targets:
+    $default:
+        builders:
+        reflectable:
+            generate_for:
+            - bin/**_controller.dart
+            options:
+            formatted: true
+    ```
+
+## Known limitation
+
+* Reflection on functions/closures
+* Reflection on private declarations
+* Reflection on generic type
