DanTDM's lab map (newbie)

Hi guys,

I'm a newbie and need help on this please :
I've downloaded this map for DanTDM's lab
http://www.minecraftworldmap.com/worlds/Yw6hz#/-863/64/-31/-5/0/0
But the thing is... once downloaded, HOW DO I USE IT ?

Sorry about that, I've got this Lab folder now but don't have a clue what to do with it.
Can you guys help please ?

Thank you so much.
A smile,

Sehb.
