Multisite subdomain wildcard

Hi there,

I try to install an multisite on a shared hosting.
I created setup.php and all the env/ thing...

I'm just stuck on the domain "setup". The documentation says : " If you choose sub-domains for structuring your website network, then you will have to configure (wildcard) sub-domains on your server in addition to the setup of your subsites in your user/env directory."

But what is this configuration (wildcard) that I need to set up ? Do we have to redirect * to main domain ?

Thanks for the help.
Cheers,
thomas
