Locking up a f800st

[Spavin]

As the title suggests, I have a disc lock for the front wheel but have no idea how to route a chain, I'm assuming it goes through the frame/swing arm and rear wheel at some point rather than just round a wheel? I know it seems a really stupid question, but I've never had a bike before and it's silly things like this that seem to be confusing me
Thanks

I picked up a 1.5m oxford hardcore xl as it satisfies the insurance, I know its not anywhere near the best around but it should suffice for any opportunists where the bikes being kept at work.
