# Integration

[`json.hpp`](https://github.com/nlohmann/json/blob/develop/single_include/nlohmann/json.hpp) is the single required file in `single_include/nlohmann` or [released here](https://github.com/nlohmann/json/releases). You need to add
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
#include <nlohmann/json.hpp>
|
||
|
|
|
||
|
|
// for convenience
|
||
|
|
using json = nlohmann::json;
|
||
|
|
```
|
||
|
|
|
||
|
|
to the files you want to process JSON and set the necessary switches to enable C++11 (e.g., `-std=c++11` for GCC and Clang).
|
||
|
|
|
||
|
|
You can further use file [`include/nlohmann/json_fwd.hpp`](https://github.com/nlohmann/json/blob/develop/include/nlohmann/json_fwd.hpp) for forward-declarations. The installation of json_fwd.hpp (as part of cmake's install step), can be achieved by setting `-DJSON_MultipleHeaders=ON`.
