-Wrapping a `struct` as `PyObject`
\ No newline at end of file
+Add `PY_CLASS` macro into your `struct` and implement a static function `_register`.
+
+```cpp
+PY_CLASS(T, mod, name)
+```
+
+## Example
+
+```cpp
+#include "pocketpy.h"
+
+using namespace pkpy;
+
+struct Vector2 {
+    PY_CLASS(Vector2, test, Vector2)
+    float x;
+    float y;
+
+    Vector2(float x, float y) : x(x), y(y) {}
+
+    static void _register(VM* vm, PyObject* mod, PyObject* type){
+        vm->bind_static_method<2>(type, "__new__", [](VM* vm, ArgsView args){
+            float x = vm->num_to_float(args[0]);
+            float y = vm->num_to_float(args[1]);
+            return VAR_T(Vector2, x, y);
+        });
+
+        vm->bind_method<0>(type, "__repr__", [](VM* vm, ArgsView args){
+            Vector2& self = CAST(Vector2&, args[0]);
+            std::stringstream ss;
+            ss << "Vector2(" << self.x << ", " << self.y << ")";
+            return VAR(ss.str());
+        });
+
+        vm->bind_method<1>(type, "__add__", [](VM* vm, ArgsView args){
+            Vector2& self = CAST(Vector2&, args[0]);
+            Vector2& other = CAST(Vector2&, args[1]);
+            return VAR_T(Vector2, self.x + other.x, self.y + other.y);
+        });
+
+        vm->bind_method<1>(type, "__sub__", [](VM* vm, ArgsView args){
+            Vector2& self = CAST(Vector2&, args[0]);
+            Vector2& other = CAST(Vector2&, args[1]);
+            return VAR_T(Vector2, self.x - other.x, self.y - other.y);
+        });
+
+        vm->bind_method<1>(type, "__mul__", [](VM* vm, ArgsView args){
+            Vector2& self = CAST(Vector2&, args[0]);
+            f64 other = vm->num_to_float(args[1]);
+            return VAR_T(Vector2, self.x * other, self.y * other);
+        });
+
+        vm->bind_method<1>(type, "__truediv__", [](VM* vm, ArgsView args){
+            Vector2& self = CAST(Vector2&, args[0]);
+            f64 other = vm->num_to_float(args[1]);
+            return VAR_T(Vector2, self.x / other, self.y / other);
+        });
+
+        vm->bind_method<1>(type, "__eq__", [](VM* vm, ArgsView args){
+            Vector2& self = CAST(Vector2&, args[0]);
+            Vector2& other = CAST(Vector2&, args[1]);
+            return VAR(self.x == other.x && self.y == other.y);
+        });
+
+        vm->bind_method<1>(type, "__ne__", [](VM* vm, ArgsView args){
+            Vector2& self = CAST(Vector2&, args[0]);
+            Vector2& other = CAST(Vector2&, args[1]);
+            return VAR(self.x != other.x || self.y != other.y);
+        });
+    }
+};
+
+int main(){
+    VM* vm = new VM(true);
+    // create a new module `test`
+    PyObject* mod = vm->new_module("test");
+    // register `Vector2` to `test` module
+    Vector2::register_class(vm, mod);
+    return 0;
+}
+```
+
+## Usage
+
+```python
+from test import Vector2
+
+a = Vector2(1.0, 2.0)
+b = Vector2(-1.0, -2.0)
+print(a + b)    # Vector2(0.0, 0.0)
+```
