 - **Trivial integration**. Our whole code consists of just two files: A header file `JSON.h` and a source file `JSON.cc`. That's it. No library, no subproject, no dependencies. The class is written in vanilla C++98 and -- if possible -- uses some features of C++11 such as move constructors. All in all, the class should require no adjustment of your compiler flags or project settings.
 
-- **Intiuitve syntax**. In languages such as Python, JSON feels like a first class data type. We used all the operator magic of C++ to achieve the same feeling in your code. Check out the examples below and you know, what I mean.
