 Plugin Framework for Java (PF4J)
 =====================
-
 A plugin is a way for a third party to extend the functionality of an application. A plugin implements extension points
 declared by application or other plugins. Also a plugin can define extension points.
 
-Components
+Features/Benefits
 -------------------
+With PF4J you can easily transform a monolithic java application in a modular application. 
+PF4J is an open source (Apache license) tiny Java library (around 35KB), with minimal dependencies and very extensible (see PluginDescriptorFinder and ExtensionFinder).
+
+No XML, only Java.
 
+You can mark any interface or abstract class as an extension point (with marker interface ExtensionPoint) and you specified that an class is an extension with @Extension annotation.
+
+Components
+-------------------
 - **Plugin** is the base class for all plugins types. Each plugin is loaded into a separate class loader to avoid conflicts.
 - **PluginManager** is used for all aspects of plugins management (loading, starting, stopping).
 - **ExtensionPoint** is a point in the application where custom code can be invoked. It's a java interface marker.   
 
 Artifacts
 -------------------
-
 - PF4J `pf4j` (jar)
 - PF4J Demo `pf4j-demo` (executable jar)
 
 Using Maven
 -------------------
-
 In your pom.xml you must define the dependencies to PF4J artifacts with:
 
 ```xml
 
 How to use
 -------------------
-
 It's very simple to add pf4j in your application:
 
     public static void main(String[] args) {
 
 Demo
 -------------------
-
 I have a tiny demo application. The demo application is in demo folder.
 In demo/api folder I declared an extension point (_Greeting_).  
 In demo/plugin* I implemented two plugins: plugin1, plugin2 (each plugin adds an extension for _Greeting_).
