 ####To use the library
 
-  * First create a `gmenu::Menu` object, the will constructor need:
+  * First Need to decide the menu items, ie the options available (eg Start, Exit, Highscore etc)
+  * Create A vector of `gmenu::MenuItem`. Which contains the title of the item and Action it will perform.
 
-    * `sf::Renderwindow *` the main screen where Menu will be displayed.
-    *  `std::string` Menu title - The main heading of menu
-    *  `sf::Font` The font title will be displayed in
-    *  `gmenu::MenuItems *` This is an pointer to array of **MenuItem - the structure representing a menu option**.
+  The definition of `gmenu::MenuItem` is:
+    
+    ```cpp
+       struct MenuItem {
+           std::shared_ptr<Action> action;
+           std::string title;
+       };
+    ```
+    
+     Here `gmenu::Action` is an abstract Class that acts as an interface.
+     The virtual method `bool DerivedAction::start()` will be called by the Menu when that item is selected.
+    
+ 
+* Now create a style. `gmenu::Style`
+     * It requires two paramenters ( `sf::Font` ) to initialize.
+     * `gmenu::Style` can be used to define the look of the menu.
+     
+     ```cpp
+      sf::Font &TitleFont;
+      sf::Font &ItemFont;
+
+      sf::Color TitleColor = sf::Color::Green;;
+      sf::Color ItemColor = sf::Color::Red ;
+      sf::Color Selected = sf::Color::Blue; 
+
+      unsigned int TitleFontSize = 50;
+      unsigned int ItemFontSize = 20;
+
+      float MenuTitleScaleFactor = 0.125; //This scale determines the distance between Title and the first option
+      float MenuItemScaleFactor = 0.25; // This determines the distance between options. 
 
-      ```cpp
-        struct MenuItem {
-          Action *action;
-          std::string title;
-          sf::Font font;
-        };
-      ```
-        Here `Action` is an **abstract class** with one virtual method `bool start` This is where you will implement the action to be performed when the option is selected.
-        
-*  `menu.createMenu()` to start the menu
+      int layout = Layout::Default; // Bitflag, Defines the layout of menu. eg. Layout::ItemLeft| Layout::TitleCentre
+
+      struct {
+       signed int top, left;
+      } Padding; // this is the padding that will extra displacement that will always be added.
+     ```
+     
+* Now create an object of `gmenuMenu` which require the following parameters:
+  * `sf::RenderWindow` : Where menu is to be created
+  * `std::vector<gmenu::MenuItem>` : Vector containing MenuItems.
+  * `gmenu::Style`: That defines the style.
+ 
+* Vola, your menu is ready to be used.
