 ## Installation
 Copy the folder Reflectpp/ into your project and add it to your include path
 
-Please refer to the [wiki](https://github.com/Zal0/Reflectpp/wiki "wiki") for usage instructions
+## Usage
+Instead of declaring your classes like
+```cpp
+enum Level
+{
+	LOW = 1,
+	MEDIUM = 5,
+	HIGH = 10,
+};
+
+class N {
+public:
+	int n_int;
+	float n_float;
+	std::string n_string;
+	Vector3 n_vector3;
+	std::vector< int > n_float_vector_array[2];
+	Level level;
+
+	N() : n_int(0), n_float(1.0f), n_string("str"), level(LOW) {
+		n_float_vector_array[0].push_back(1);
+		n_float_vector_array[0].push_back(2);
+
+		n_float_vector_array[1].push_back(10);
+		n_float_vector_array[1].push_back(20);
+		n_float_vector_array[1].push_back(30);
+	}
+};
+```
+Use the corresponding Reflectpp macros
+```cpp
+#define ENUM_NAME Level
+#define ENUM_ENTRIES \
+	ENUM_ENTRY(LOW, 1) \
+	ENUM_ENTRY(MEDIUM, 5) \
+	ENUM_ENTRY(HIGH, 10)
+#include "ReflectEnumDecl.h"
+
+REFLECTABLE_CLASS(N)
+	#define REFLECTION_DATA   \
+		SERIALIZED_FIELD(public, int, n_int)\
+		SERIALIZED_FIELD(public, float, n_float)\
+		SERIALIZED_FIELD(public, std::string, n_string)\
+		SERIALIZED_FIELD(public, Vector3, n_vector3)\
+		SERIALIZED_FIELD(public, std::vector< int >, n_float_vector_array[2])\
+		SERIALIZED_FIELD(public, Level, level)
+	#include "ReflectDecl.h"
+
+	N() : n_int(0), n_float(1.0f), n_string("str"), level(LOW) {
+		n_float_vector_array[0].push_back(1);
+		n_float_vector_array[0].push_back(2);
+
+		n_float_vector_array[1].push_back(10);
+		n_float_vector_array[1].push_back(20);
+		n_float_vector_array[1].push_back(30);
+	}
+};
+```
+then you will be able to
+```cpp
+N n;
+
+//Iterate N contents
+ReflectInfoIterator it(&n);
+ReflectField info;
+while((info = it.Next()).reflectable)
+{
+	printf("%s: %s\n", info.infos->id, info.ToString().c_str());
+}
+
+
+//Access fields using reflection
+n.Get("n_int").Set< int >(4); //n.n_int == 4
+n.Get("n_float_vector_array[0][0]").Set< int >(999); //n_float_vector_array[0][0] == 99
+n.Get("n_float_vector_array[0]").GetVectorHandler()->Push(); //added new element into n_float_vector_array[0] 
+PrintReflectable(&n);
+
+//Serialize into json
+Serialize(&n, "n.json");
+
+//Deserialize from json
+Deserialize(&n, "n_mod.json");
+PrintReflectable(&n);
+```
