+This is the core library used to handle games, build platforms, extensions and tools for GDevelop. The editor is based on classes and tools offered by this library.
 
-Getting started
----------------
+GDevelop Core is a portable C++ library, compiled to be used in JavaScript in the editor.
+
+## 1) Getting started 🤓
 
 First, take a look at the *Readme.md* at the root of the repository and the [developer documentation](http://4ian.github.io/GD-Documentation/).
 
-Contributing
-------------
+## 2) How to contribute 😎
 
 Any contribution is welcome! Whether you want to submit a bug report, a feature request
 or any pull request so as to add a nice feature, do not hesitate to get in touch.
 
+* Check the [the **roadmap** for ideas and features planned](https://trello.com/b/qf0lM7k8/gdevelop-roadmap).
+  
+* Follow the [Development](https://github.com/4ian/GDevelop/tree/master/newIDE#development) section of the README to set up GDevelop and start modifying either **the editor** or **[the game engine/extensions](https://github.com/4ian/GDevelop/tree/master/newIDE#development-of-the-game-engine-or-extensions)**.
+
+* To submit your changes, you have first to create a Fork on GitHub (use the Fork button on the top right), then [create a Pull Request](https://help.github.com/articles/creating-a-pull-request-from-a-fork/).
