+Introduction
+============
+
+ChaiScript is one of the only embedded scripting language designed from the 
+ground up to directly target C++ and take advantage of modern C++ development 
+techniques, working with the developer like he expects it to work.  Being a 
+native C++ application, it has some advantages over existing embedded scripting 
+languages:
+
+1) It uses a header-only approach, which makes it easy to integrate with 
+   existing projects.
+2) It maintains type safety between your C++ application and the user scripts.
+3) It supports a variety of C++ techniques including callbacks, overloaded 
+   functions, class methods, and stl containers.
+
+Requirements
+============
+
+ChaiScript requires a recent version of Boost (http://www.boost.org) to build.
+
+Usage
+=====
+
+* Add the ChaiScript include directory to your project's header search path
+* Add `#include <chaiscript/chaiscript.hpp>` to your source file
+* Instantiate the ChaiScript engine in your application.  For example, create 
+  a new engine with the name `chai` like so: `chaiscript::ChaiScript chai`
+
+Once instantiated, the engine is ready to start running ChaiScript source.  You 
+have two main options for processing ChaiScript source: a line at a time using 
+`chai.eval(string)` and a file at a time using `chai.eval_file(fname)`
+
+To make functions in your C++ code visible to scripts, they must be registered 
+with the scripting engine.  To do so, call add:
+
+    chai.add(chaiscript::fun(&my_function), "my_function_name");
+
+Once registered the function will be visible to scripts as "my_function_name"
+
+Examples
+========
+
+ChaiScript is similar to ECMAScript (aka JavaScript(tm)), but with some 
+modifications to make it easier to use.  For usage examples see the "samples" 
+directory, and for more in-depth look at the language, the unit tests in the 
+"unittests" directory cover the most ground.
+
+For examples of how to register parts of your C++ application, see 
+"example.cpp" in the "src" directory. Example.cpp is verbose and shows every 
+possible way of working with the library. For further documentation generate 
+the doxygen documentation in the build folder or see the website 
+http://www.chaiscript.com.
+
+
+The shortest complete example possible follows:
+
+    /// main.cpp
+
+    #include <chaiscript/chaiscript.hpp>
+
+    double function(int i, double j)
+    {
+      return i * j;
+    }
+
+    int main()
+    {
+      chaiscript::ChaiScript chai;
+      chai.add(chaiscript::fun(&function), "function");
+
+      double d = chai.eval<double>("function(3, 4.75);");
+    }
