 The easiest way to start is to use [Wasienv](https://github.com/wasienv/wasienv).
 
-Create `hello.c`:
+### C/C++ WASI app
-```c
-#include <stdio.h>
-
-int main()
-{
-   printf("Hello, %s!\n", "world");
-   return 0;
-}
-```
-
-```sh
-$ wasicc -O3 -Wl,--stack-first hello.c -o hello.wasm
-
-$ wasm3 hello.wasm                      
-Hello, world!
-```
-
-### C++ WASI app
 
 Create `hello.cpp`:
 ```cpp
 #include <iostream>
-
+int main() {
-int main()
+    std::cout << "Hello, world!" << std::endl;
-{
-    std::cout << "Hello World!" << std::endl;
     return 0;
 }
 ```
 
+Or `hello.c`:
+```c
+#include <stdio.h>
+int main() {
+   printf("Hello, %s!\n", "world");
+   return 0;
+}
+```
+
 ```sh
-$ wasic++ -O3 -Wl,--stack-first hello.cpp -o hello.wasm
+$ wasic++ -O3 hello.cpp -o hello.wasm
+$ wasicc -O3 hello.c -o hello.wasm
 
 $ wasm3 hello.wasm
 Hello World!
 ```
