You have to install their software to get the Steam key.
I highly recommend this game, it's one of the gems of the last years.
To maximize your enjoyment of Fallout NV
1. Install the mods Project Nevada and New Vegas Bounties 1+2 (and the large community patch). They both add so much to the vanilla game without changing the core experience. I recommend them even for the first playthrough. They are similarly crucial like Stalker Complete Mods to the Stalkers.
2. Play the DLCs in the story-chronological order:
- Honest Hearts (which I found was the weakest one)
- Dead Money
- Old World Blues
- Lonesome Road
