+## Getting Started
+
+#### C/C++
+
+For C/C++ developers, you can download the `pocketpy.h` on our GitHub release page.
+
+https://github.com/blueloveTH/pocketpy/releases/latest
+
+Check [C-API](https://pocketpy.dev/c-api/vm/) for references.
+
+```cpp
+#include "pocketpy.h"
+
+int main(){
+    // Create a virtual machine
+    VM* vm = pkpy_new_vm(true);
+    // Exec some code
+    pkpy_vm_exec(vm, "print('Hello world!')");
+    return 0;
+}
+```
+
+#### Unity Engine
+
+PocketPy for Unity can be installed via Unity Asset Store.
+
+https://assetstore.unity.com/packages/slug/241120
+
+```csharp
+using UnityEngine;
+
+public class Test01 : MonoBehaviour
+{
+    // Start is called before the first frame update
+    void Start()
+    {
+        // Create a virtual machine
+        pkpy.VM vm = new pkpy.VM();
+
+        // Create a list
+        vm.exec("a = [1, 2, 3]");
+
+        // Eval the sum of the list
+        string result = vm.eval("sum(a)");
+        Debug.Log(result);   // 6
+
+        // Print to the standard output
+        vm.exec("print(a)");
+        pkpy.PyOutput o = vm.read_output();
+        Debug.Log(o.stdout); // [1, 2, 3]
+
+        // Create a binding
+        vm.bind("builtins", "test", (double x) => x+1);  
+        Debug.Log(vm.eval("test(3.14)")); // '4.14'
+    }
+}
