The only instance of "waf" is in the root of the workspace. Why would I be getting:

> Executing task: waf AP_Periph <

zsh:1: command not found: waf
The terminal process "/bin/zsh '-c', 'waf AP_Periph'" terminated with exit code: 127.

Press any key to close the terminal.

and i have this in my tasks.json file:

            "options": {
                "cwd": "${workspaceFolder}/"
            },

What else should I be doing? Thanks.

My Os is win 10

I install this extension in my visual studio code ,
but there is nothing change in the UI,

there is waf and wscript in the root of workspace

is there a document show how to use it ?

Thanks!
