+About ZEngine 0.7.x
+
+ZEngine is a game library which is designed to compile that SDL and OpenGL
+are available on.  ZEngine is a set of classes and a main ZEngine class which
+are designed to make game development easier and more organized.  As of 0.7.7
+ZEngine uses OpenGL to do the 2D display, so it is much faster and can take
+advantage of hardware accelerated features. 
+
+Building ZEngine:
+
+ZEngine can be built on any system that has SDL and OpenGL available.  It is
+currently being developed on Redhat 8.0 and Windows 2000/XP.  If you are on
+windows the folder vc7 contains project files for use, and if you are using
+mingw or cygwin you can replace the linux makefile with makefile.mingw32.
+-If you are using VC++ you will need to add the path to the dependencies (SDL 
+and others) as well as the path to ZEngine before building.
+-If you are using gcc on any system you will need to modify the makefile you
+are using to set the proper include and lib paths.
+If you are having a problem building ask on http://conceptofzero.net/forums.
+
+Using ZEngine:
+
+Using ZEngine is as easy as having a look at the sample programs and nice
+documentation provided and setting the compiler to link with the ZEngine lib
+and include the ZEngine include files.  ZEngine allows you to decide what 
+external libraries (other than SDL and OpenGL which are required) you want
+to use when you build the library file.  Depending on which libraries you are
+using you will need to distribute various files with your program, but none
+are part of ZEngine, but instead are files in use by the dependencies.
+
+Legal Overview:
+
+The world of open source licenses can be confusing, if you are not familiar 
+with the LGPL I recommend reading it, as most libraries ZEngine makes use of
+are licensed under it.  ZEngine itself has no real restrictions on use, and is
+under the OSI-certified BSD license (see licensing.txt). Below are quick
+guides of how you would distribute various packages making use of ZEngine.
+
+Closed-Source Application using ZEngine:
+    -Include required DLLs or .so dynamic modules
+    -Include notice of which libraries you used, and have a place for them to
+    dowload them from your website.
+    -If you are using non-LGPL libraries there may be other requirements.
+    (Open-Source applications do not need to have a link to a download for
+    LGPL-licensed libraries.)
+    
+Adding to ZEngine:
+    -This can currently be done with no restrictions, but we do ask that 
+    you submit your changes back to the community.
