 ## Requirements
 
-- Llvm 11
+- MacOS
+- Llvm 11 - Llvm 12 is not supported
 - RapidJson 1.x
 
 You might need to give the path to the llvm folder to CMake:
 ```bash
+brew install llvm@11 rapidjson ninja
 mkdir builds && cd builds
-cmake .. -G Ninja -DCMAKE_PREFIX_PATH=<your_path_to_llvm_install>
+cmake .. -G Ninja -DCMAKE_PREFIX_PATH=$(brew --prefix llvm@11)
 ninja
 ```
-With brew you can print the path using:
-```bash
-brew --prefix llvm
-```
-```bash
-cmake .. -G Ninja -DCMAKE_PREFIX_PATH="$(brew --prefix llvm)"
-```
-
-## Example
-File test_example.hpp:
-```c++
-#ifndef CPP2JSON_TEST_EXAMPLE_HPP
-#define CPP2JSON_TEST_EXAMPLE_HPP
-#include <string>
-
-struct Example01
-{
-    float m_float;
-    std::string m_string;
-    int m_int;
-};
 
-#endif //CPP2JSON_TEST_EXAMPLE_HPP
-```
-
-Run cpp2json on it:
-```bash
-$> cpp2json test_example.hpp --pretty --
-```
-
-Will give you the following JSON output:
-```json
