+
+```
+chaiscript::ChaiScript chai; // loads stdlib from loadable module on file system
+chaiscript::ChaiScript chai(chaiscript::Std_Lib::library()); // compiles in stdlib
+```
+
+# Adding Things To The Engine
+
+## Adding a Function / Method / Member
+
+### General
+
+```
+chai.add(chaiscript::fun(&function_name), "function_name");
+chai.add(chaiscript::fun(&Class::method_name), "method_name");
+chai.add(chaiscript::fun(&Class::member_name), "member_name");
+```
+
+### With Overloads 
+
+#### Preferred
+
+```
+chai.add(chaiscript::fun<ReturnType (ParamType1, ParamType2)>(&function_with_overloads), "function_name");
+```
+
+#### Alternative
+
+```
+chai.add(chaiscript::fun(std::static_cast<ReturnType (*)(ParamType1, ParamType2)>(&function_with_overloads)), "function_name");
+```
+
+### Lambda
+
+```
+chai.add(
+  chaiscript::fun<std::string (bool)>(
+    [](bool type) { 
+      if (type) { return "x"; } 
+      else { return "y"; } 
+    }), "function_name");
+```
+
+### Constructors
+
+```
+chai.add(chaiscript::constructor<MyType ()>(), "MyType");
+chai.add(chaiscript::constructor<MyType (const MyType &)>(), "MyType");
+```
+
+## Adding Types
+
+It's not strictly necessary to add types, but it helps with many things. Cloning, better errors, etc.
+
+```
+chai.add(chaiscript::user_type<MyClass>, "MyClass");
+```
+
+## Adding Objects
+
+```
+chai.add(chaiscript::var(somevar), "somevar"); // copied in
+chai.add(chaiscript::var(std::ref(somevar), "somevar"); // by reference, shared between C++ and chai
+auto shareddouble = std::make_shared<double>(4.3);
+chai.add(chaiscript::var(shareddouble), "shareddouble"); // by shared_ptr, shared between c++ and chai
+chai.add(chaiscript::const_var(somevar), "somevar"); // copied in and made const
+chai.add_global_const(chaiscript::const_var(somevar), "somevar"); // global const. Throws if value is non-const
+chai.add_global(chaiscript::var(somevar), "somevar"); // global non-const
+```
+
+# Executing Script
+
+## General
+
+```
+chai.eval("print(\"Hello World\")");
+chai.eval(R"(print("Hello World"))");
+```
+
+## Unboxing Return Values
+
+### Prefered
+
+```
+chai.eval<double>("5.3 + 2.1"); // returns 7.4 as a C++ double
+```
+
+### Alternative
+
+```
+auto v = chai.eval("5.3 + 2.1");
+chai.boxed_cast<double>(v); // extracts double value from boxed_value and applies known conversions
+chaiscript::boxed_cast<double>(v); // free function version, does not know about conversions
+```
+
+### Converting Between Algebraic Types
+
+```
+chaiscript::Boxed_Number(chai.eval("5.3 + 2.1")).get_as<int>(); // works with any number type
+// which is equivalent to, but much more automatic than:
+static_cast<int>(chai.eval<double>("5.3+2.1")); // this version only works if we know that it's a double
+```
+
+## Sharing Values
+
+```
+double &d = chai.eval("var i = 5.2; i"); // d is now a reference to i in the script
+std::shared_ptr<double> d = chai.eval("var i = 5.2; i"); // same result but reference counted
+
+d = 3;
+chai.eval("print(i)"); // prints 3
+```
+
+## Catching Eval Errors
+
+```
+try {
+  chai.eval("2.3 + \"String\"");
+} catch (const chaiscript::exception::eval_error &e) {
+  std::cout << "Error\n" << e.pretty_print() << '\n';
+}
+```
+
+## Catching Errors Thrown From Script
+
+```
+try {
+  chai.eval("throw(runtime_error(\"error\"))", chaiscript::exception_specification<int, double, float, const std::string &, const std::exception &>());
+} catch (const double e) {
+} catch (int) {
+} catch (float) {
+} catch (const std::string &) {
+} catch (const std::exception &e) {
+  // This is the one what will be called in the specific throw() above
+}
+```
+
+## Sharing Functions
+
+
+```
+auto p = chai.eval<std::function<std::string (double)>>("to_string"); 
+p(5); // calls chaiscript's 'to_string' function, returning std::string("5")
+```
+
+Note: backtick treats operators as normal functions
+
+```
+auto p = chai.eval<std::function<int (int, int)>>(`+`); 
+p(5, 6); // calls chaiscript's '+' function, returning 11
+```
+
+```
+auto p = chai.eval<std::function<std::string (int, double)>>(fun(x,y) { to_string(x) + to_string(y); });
+p(3,4.2); // evaluates the lambda function, returning the string "34.2" to C++
+```
+
+# Language Reference
+
+## Variables
+
+```
+var i; // uninitialized variable, can take any value on first assignment;
+auto j; // equiv to var
+
+var k = 5; // initialized to 5 (integer)
+var l := k; // reference to k
+auto &m = k; // reference to k
+
+GLOBAL g = 5; // creates a global variable. If global already exists, it is not re-added
+GLOBAL g = 2; // global 'g' now equals 2
+
+GLOBAL g2;
+if (g2.is_var_undef()) { g2 = 4; } // only initialize g2 once, if GLOBAL decl hit more than once
+```
+
+## Built in Types
+
+```
+var v = [1,2,3u,4ll,"16", `+`]; // creates vector of heterogenous values
+var m = ["a":1, "b":2]; // map of string:value pairs
+```
+
+Floating point values default to `double` type and integers default to `int` type. All C++ suffixes
+such as `f`, `ll`, `u` as well as scientific notion is supported
+
+```
+1.0 // double
+1.0f // float
+1.0l // long double
+1 // int
+1u // unsigned int
+1ul // unsigned long
+1ull // unsigned long long
+```
+
+Literals are automatically sized, just as in C++. For example: `10000000000` is > 32bits and the appropriate type is used to hold it
+on your platform.
+
+
+## Functions
+
+### General 
+
+```
+def myfun(x, y) { x + y; } // last statement in body is the return value
+def myfun(x, y) { return x + y; } // equiv 
+```
+
+### Optionally Typed
+
+```
+def myfun(x, int y) { x + y; } // requires y to be an int
+```
+
+### With Guards
+
+```
+def myfun(x, int y) : y > 5 { x - y; } // only called if y > 5
+```
+
+### Methods
+
+Methods and functions are mostly equivalent
+
+```
+def string::add(int y) { this + to_string(y); }
+def add(string s, int y) { s + to_string(y); } //equiv functionality
+
+// calling new function/method
+"a".add(1); // returns a1
+add("a", 1); // returns a1, either calling syntax works with either def above
+```
+
+### Lambdas
+
+```
+var l = fun(x) { x * 15; }
+l(2) // returns 30
+
+var a = 13
+var m = fun[a](x) { x * a; } 
+m(3); // a was captured (by reference), returns 39
+
+var n = bind(fun(x,y) { x * y; }, _, 10);
+n(2); // returns 20 
+```
+
+
+
+## ChaiScript Defined Types
+
+Define a type called "MyType" with one member value "a" and a getter
+
+### Preferred
+
+```
+class MyType {
+  var value;
+  def MyType() { this.value = "a"; }
+  def get_value() { "Value Is: " + this.value; }
+};
+```
+
+### Alternative 
+
+```
+attr MyType::value;
+def MyType::MyType() { this.value = "a"; }
+def MyType::get_value() { "Value Is: " + this.value; }
+```
+
+### Using
+
+```
+var m = MyType(); // calls constructor
+print(m.get_value()); // prints "Value Is: a"
+print(get_value(m)); // prints "Value Is: a"
+```
+
+## Dynamic Objects
+
+All ChaiScript defined types and generic Dynamic_Object support dynamic parameters
+
+```
+var o = Dynamic_Object();
+o.f = fun(x) { print(x); }
+o.f(3); // prints "3"
+```
+
+Implicit 'this' is allowed:
+
+```
+var o = Dynamic_Object();
+o.x = 3;
+o.f = fun(y) { print(this.x + y); }
+o.f(10); // prints 13
+```
+
+## method_missing
+
+A function of the signature `method_missing(object, name, param1, param2, param3)` will be called if an appropriate
+method cannot be found
+
+```
+def method_missing(int i, string name, Vector v) {
+  print("method_missing(${i}, ${name}), ${v.size()} params");
+}
+
+5.bob(1,2,3); // prints "method_missing(5, bob, 3 params)"
+```
+
+`method_missing` signature can be either 2 parameters or 3 parameters. If the signature contains two parameters
+it is treated as a property. If the property contains a function then additional parameters are passed to
+the contained function.
+
+If both a 2 parameter and a 3 parameter signature match, the 3 parameter function always wins.
+
+
+# Built In Functions
+
+## Evaluation
+
+```
+eval("4 + 5") // dynamically eval script string and returns value of last statement
+eval_file("filename") // evals file and returns value of last statement
+use("filename") // evals file exactly once and returns value of last statement
+                // if the file had already been 'used' nothing happens and undefined is returned
+```
+
+Both `use` and `eval_file` search the 'usepaths' passed to the ChaiScript constructor

-  /// if you have a type that is introduced in a loadable module and is used by multiple modules

-  /// \code
-  /// class Base
-  /// {};
-  /// class Derived : public Base

-  ///
-  /// chaiscript::ChaiScript chai;

 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:

 Requirements
 ============
 
-ChaiScript requires a recent version of Boost (http://www.boost.org) to build.
+ChaiScript requires a C++11 compiler to build with support for variadic 
+templates.  It has been tested with gcc 4.6 and clang 3.1 (with libcxx). MacOS 
+10.8 (Mountain Lion) is also known to support the C++11 build with Apple's 
+clang 4.0. MSVC 2013 or newer is supports also. For more information see the build 
+[dashboard](http://chaiscript.com/ChaiScript-BuildResults/index.html).
 
 Usage
