Q: How do I get my external display to show while my laptop lid is closed? How do I stop the laptop from going to sleep?

I want to use an external display via HDMI from my MacBookPro.  But I want to close my laptop and whenever I do the whole laptop goes to sleep and the external display goes black.  What do I do to make the laptop stay on when I close it up?>

Thank you
