+## Introduction
+
+RapidJSON is a JSON parser and generator for C++. It was inspired by [RapidXml](http://rapidxml.sourceforge.net/).
+
+* RapidJSON is **small** but **complete**. It supports both SAX and DOM style API. The SAX parser is only a half thousand lines of code.
+
+* RapidJSON is **fast**. Its performance can be comparable to `strlen()`. It also optionally supports SSE2/SSE4.2 for acceleration.
+
+* RapidJSON is **self-contained** and **header-only**. It does not depend on external libraries such as BOOST. It even does not depend on STL.
+
+* RapidJSON is **memory-friendly**. Each JSON value occupies exactly 16 bytes for most 32/64-bit machines (excluding text string). By default it uses a fast memory allocator, and the parser allocates memory compactly during parsing.
+
+* RapidJSON is **Unicode-friendly**. It supports UTF-8, UTF-16, UTF-32 (LE & BE), and their detection, validation and transcoding internally. For example, you can read a UTF-8 file and let RapidJSON transcode the JSON strings into UTF-16 in the DOM. It also supports surrogates and "\u0000" (null character).
+
+More features can be read [here](doc/features.md).
+
+JSON(JavaScript Object Notation) is a light-weight data exchange format. RapidJSON should be in full compliance with RFC7159/ECMA-404, with optional support of relaxed syntax. More information about JSON can be obtained at
+* [Introducing JSON](http://json.org/)
+* [RFC7159: The JavaScript Object Notation (JSON) Data Interchange Format](https://tools.ietf.org/html/rfc7159)
+* [Standard ECMA-404: The JSON Data Interchange Format](https://www.ecma-international.org/publications/standards/Ecma-404.htm)
+
+## Highlights in v1.1 (2016-8-25)
+
+* Added [JSON Pointer](doc/pointer.md)
+* Added [JSON Schema](doc/schema.md)
+* Added [relaxed JSON syntax](doc/dom.md) (comment, trailing comma, NaN/Infinity)
+* Iterating array/object with [C++11 Range-based for loop](doc/tutorial.md)
+* Reduce memory overhead of each `Value` from 24 bytes to 16 bytes in x86-64 architecture.
+
+For other changes please refer to [change log](CHANGELOG.md).
+
+## Compatibility
+
+RapidJSON is cross-platform. Some platform/compiler combinations which have been tested are shown as follows.
+* Visual C++ 2008/2010/2013 on Windows (32/64-bit)
+* GNU C++ 3.8.x on Cygwin
+* Clang 3.4 on Mac OS X (32/64-bit) and iOS
+* Clang 3.4 on Android NDK
+
+Users can build and run the unit tests on their platform/compiler.
+
+## Installation
+
+RapidJSON is a header-only C++ library. Just copy the `include/rapidjson` folder to system or project's include path.
+
+Alternatively, if you are using the [vcpkg](https://github.com/Microsoft/vcpkg/) dependency manager you can download and install rapidjson with CMake integration in a single command:
+* vcpkg install rapidjson
+
+RapidJSON uses following software as its dependencies:
+* [CMake](https://cmake.org/) as a general build tool
+* (optional) [Doxygen](http://www.doxygen.org) to build documentation
+* (optional) [googletest](https://github.com/google/googletest) for unit and performance testing
+
+To generate user documentation and run tests please proceed with the steps below:
+
+1. Execute `git submodule update --init` to get the files of thirdparty submodules (google test).
+2. Create directory called `build` in rapidjson source directory.
+3. Change to `build` directory and run `cmake ..` command to configure your build. Windows users can do the same with cmake-gui application.
+4. On Windows, build the solution found in the build directory. On Linux, run `make` from the build directory.
+
+On successful build you will find compiled test and example binaries in `bin`
+directory. The generated documentation will be available in `doc/html`
+directory of the build tree. To run tests after finished build please run `make
+test` or `ctest` from your build tree. You can get detailed output using `ctest
+-V` command.
+
+It is possible to install library system-wide by running `make install` command
+from the build tree with administrative privileges. This will install all files
+according to system preferences. Once RapidJSON is installed, it is possible
+to use it from other CMake projects by adding `find_package(RapidJSON)` line to
+your CMakeLists.txt.
+
+## Usage at a glance
+
+This simple example parses a JSON string into a document (DOM), make a simple modification of the DOM, and finally stringify the DOM to a JSON string.
+
+~~~~~~~~~~cpp
+// rapidjson/example/simpledom/simpledom.cpp`
+#include "rapidjson/document.h"
+#include "rapidjson/writer.h"
+#include "rapidjson/stringbuffer.h"
+#include <iostream>
+
+using namespace rapidjson;
+
+int main() {
+ // 1. Parse a JSON string into DOM.
+ const char* json = "{\"project\":\"rapidjson\",\"stars\":10}";
+ Document d;
+ d.Parse(json);
+
+ // 2. Modify it by DOM.
+ Value& s = d["stars"];
+ s.SetInt(s.GetInt() + 1);
+
+ // 3. Stringify the DOM
+ StringBuffer buffer;
+ Writer<StringBuffer> writer(buffer);
+ d.Accept(writer);
+
+ // Output {"project":"rapidjson","stars":11}
+ std::cout << buffer.GetString() << std::endl;
+ return 0;
+}
+~~~~~~~~~~
+
+Note that this example did not handle potential errors.
+
+The following diagram shows the process.
