It's not a big issue. Loads of info on Google. .... Just rub rust off with wire wool /steel brush. Paint with some oil based paint, Hammerite ect. Or mask area and spray it with car paint........Then ride it. End.
But if you kept it inside you would have alot less issues later on with the whole bike turning to shit........Or being stolen, kicked in. I would be more worried about that than the rust.
