replacing mouldy grout

Hello
I want to re-grout a couple of small areas in my bathroom which have gone mouldy over time (they are right by the shower). What's the best way to start? Can I grout over the existing, or is it best to remove old grout and put new grout in?
Have never done anything like this before so any tips would be appreciated!
Thank you.
