How to put Questions on Home Page?

I'd like the front page of my site to display the list of questions, as it does on /questions/.

Experimenting, I tried changing this...

define( 'QA_SLUG_ROOT','questions' );

to this...

define( 'QA_SLUG_ROOT','\' );

but that didn't work...

Can you clue me in on the right way to go about doing this?
Thanks!
