Best way to care for lemon-scented geranium?

Hello all. I'm very much a beginner gardener, although my parents are very much into it- they have 2 allotments!

I keep a few indoor plants, namely a Coleus, a succulent that I forget the name of, and a multicoloured African Violet. My mum's recently given me a lemon scented geranium (or is it pelagonium?) to look after, too. I always loved them when I was a kid.

Does anyone have any tips for looking after lemon-scented geraniums? Specifically, I'd like to enhance the scent if possible, but any general care tips would be great.

Thanks in advance!
