+Install + open API setup wizard:
 
 ```bash
-# Linux / macOS / WSL — replace YOUR_USER
-curl -fsSL https://raw.githubusercontent.com/YOUR_USER/arrowcode/main/install.sh | bash
+curl -fsSL https://raw.githubusercontent.com/Chintanpatel24/arrowcode/main/install.sh | bash -s -- --setup

+5. Link `arrowcode` / `ac` onto your PATH
