| [`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 |
| [`single_include/nlohmann/json_fwd.hpp`](https://github.com/nlohmann/json/blob/develop/single_include/nlohmann/json_fwd.hpp) |
| for forward declarations. |
