Vscode autocomplete and language keyword

Hi everyone,
I know I’m a total newbie on Home Assistant and trying to get into… but there are really many many things to study in a row…
Well, I’m here to kindly ask you to help on correctly setting vscode addon in order to auto-complete the yaml file and also to highlight its keyword… but possibly also to enable these features for all the other languages…

Could you please help with this ?

thanks!!!

I’m interested, too. Could someone help ?
