-## Getting started
+## About this project
 
-This page is under construction.
+This repository contains a wiki dedicated to learn how to use Unity3D in an easy way.
+It was created out of a continuing need to answer questions that new Unity3D developers had that were not clearly answered in the official Unity3D documentation.
+As a result, an effort by the community of Unity developers has been made to create this wiki and its contents.
