+  // Create a Store
+  store := wasmer.NewStore(engine)
+
+  fmt.Println("Compiling module...")
+  module, err := wasmer.NewModule(store, wasmBytes)
+
+  if err != nil {	 
+      fmt.Println("Failed to compile module:", err)
+  }
+
+  // Create an empty import object.
+  importObject := wasmer.NewImportObject()
+
+  fmt.Println("Instantiating module...")
+  // Let's instantiate the Wasm module.
+  instance, err := wasmer.NewInstance(module, importObject)
