A question about Rust

When rust came out in Beta, I managed to get hold of a key. I played it for a few months and then stopped to wait for the full and finished version to come out. WilL I have to buy the game now that its on steam, or can I enter my beta code somewhere and get it for free?

Thanks guys,

If you buy it on the Rust Homepage and get a key,you can use it for steam.

You will find all Infos here http://old.playrust.com/

I think you can take it from the other stie (http://old.playrust.com/) they giving on lower page information on how to replace key and get it on steam
