Half-Life patch problems

Apperently I can't play Half-life online without the newest update. So I made my Half Life client search for the newest pach but as you can see...

No patches are up or something. Is there a place online where I can get the patch beyond 1.1.1.0

You'll probably have to go through Steam, I'd imagine.

I have no clue how to do that.

Download and install Steam

Run it and it should update your stuff.
