Lifting - where to start?

Good news!!

Following my recent car accident I've been told my physio I'm ok to start lifting but slowly & have build up gradual (only minor shoulder/neck muscle damage but I have to be careful as it repairs)

Pre accident I was doing kettle bells at home nothing too heavy as I didn't want to build muscle, but from that you guys have posted I don't need to worry. Where I work we are opening a gym soon nothing elaborate but free weights & one weights machine (from memory) but not sure where to start. Is there a beginners programme I can follow or any other advice will be gratefully received.

Thanks in advance :-D
