Donately Documentatio

If I don’t have a campaign or fundraiser and I just want a standard form. Is the short code the same for everyone? The php code that allows you to make your form secure where should that code go? I really just need the steps spelled out for me; I’m very much a newbie. Any help with this would be greatly appreciated.
