How to install Roc

1. Open a PowerShell Terminal (you can press Win + X → Terminal).

2. Download and run the Roc installer script:

   irm https://roc-lang.org/install_roc.ps1 | iex
   

   If your PowerShell says scripts are blocked, run PowerShell as Administrator just for the install, or start it like this:

   powershell -ExecutionPolicy Bypass
   

3. Close that PowerShell window and open a new one so the updated PATH is picked up.

4. In the new PowerShell, download and run Hello World:

   curl.exe -OL https://raw.githubusercontent.com/roc-lang/roc/refs/heads/main/test/echo/hello.roc
   roc hello.roc
