+
+```
+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

 Notes:
+=======
+Current Version: 5.7.0
 
- * There was overlap during the 5.x and 4.x development cycle, so some of the notes appear twice as the new features were developed for 4.x (which required boost) then ported to 5.x (which requires C++11).
- * This is the last release of 5.x, all future development will be on the final merged 6.x line.
+### Changes since 5.6.0
 
+* Significant code cleanups and reduction
+* Smaller builds
+* Faster compiles
+* Less runtime memory usage
+* ~2x faster runtimes
+* biicode support
+* method_missing feature added #164 @arBmind
+* Generic objects with dynamic properties support
+* Add ability to call functions contained in properties
+* Add lambda captures
+* Create [cheatsheet.md](cheatsheet.md) for all-in-one reference of features
+* Fix support for libc++
+* Eliminate clone of return value stored locally
+* Eliminate 'return' statements when last line of function
+* Reduce number of runtime exceptions occuring
+* Reduce copies / moves of return values. 
+* make `use` statement return value of last statement in file
+* Add ability to access fixed array sizes
+* Add support for scientific notation floating point literals #174  @totalgee
+
+
+### Changes since 5.5.1
+* Throw exception on integer divide by 0
+* Add optional type specification to function declarations
+   
+  ```
+  def func(int i, j, double k) {
+    // i must be an int.
+    // j can be anything
+    // k must be a double
+    // normal conversion rules still apply
+  }
+   ```
+* Many minor fixes for compiler warnings
+* Add support for `std::future` and `std::async`
+  ```
+  var f := async(someFunction);
+  var f2 := async(someFunction2);
+
+  // someFunction and someFunction2 are running in parallel now
+  f.get();
+  f2.get();
+  ```
+* Fully support r-value returns, supporting move-only objects and reducing object copies
+
+
+### Changes since 5.5.0
+* 30% performance increase
+* Fix handling of object stack, resulting in greatly reduced memory usage
+* Code cleanups
+
+### Changes since 5.4.0
+* 2x performance increase
+* Significant code cleanups
+* Throw exception if user attempts to call function on null object
+* Allow user defined type conversions
+* Fix object lifetime for nested function calls made at the global scope
+* Fix returning of boolean values from function calls
+
+
+### Changes since 5.3.1
+* Decreased compile time and build size
+* Make "reflection" module built in (losing some of the time / build size gains)
+* Add new "class" syntax for ChaiScript defined methods and attributes see: [unittests/class.chai](unittests/class.chai) for examples
+* Minor performance enhancements
+* major to_string performance enhancements
+* Provide API for retrieving registered type name #124
+* Added strong reference to container to range object #132
+
+
+### Changes since 5.3.0
+* Add automatic conversion of arithmetic return types, following the same
+  rules as conversion of arithmetic types when passing parameters
+* Add automatic casting up the inheritence hierarchy when possible.
+* Enable travis.ci testing
+* Allow users to add globals from within script
+* Various static analysis fixes
+* Code modernization to C++11
+* Unofficial support for Haiku added
+* Fix #121 - Inability to compile on cygwin
+* Formatting fixes and spelling corrections
+* Apply "include what you use" https://code.google.com/p/include-what-you-use/
+* Apply clang-modernize
+* Various threading fixes
+* Performance improvements
 
 ### Changes since 5.2.0
 * Official support for MSVC with C++11. All major platforms and compilers are now support for C++11 release
+
+### Changes since 4.2.0
 * Enhanced unit tests
 * Add `continue` statement, fix various use cases for `for`  loops
 * Fix use of suffixed numbers in vector initialization
