-Welcome to your wiki!
+THE ENGINE
+==========
 
-This is the default page, edit it as you see fit. To add a new page simply reference it within brackets, e.g.: [SamplePage].
+Objective
+---------
 
-The wiki uses [Markdown](/p/theengine/wiki/markdown_syntax/) syntax.
+The goal of the project is to provide an easy-to-use games development engine for people with little spare time. 
+
+It sports a BASIC interpreter reminiscent of old 8-bit BASIC interpreters, and uses OpenGL and SDL for everything (with some exceptions).
+
+Currently, it is being developed on 64-Bit Ubuntu 12.04, with the proprietary NVidia driver. If you feel there are any compatibility issues beside the obvious, please let me know.
