Introducing 6 month old kitten, to new kitten, any advice?

Me and my bf currently have a 6 month old kitten called Jiji, he’s the best, he’s super sociable, loving and overall loves a good cuddle. We knew from the moment we got him we wanted to get another kitten before a year as I know the younger you introduce kittens together the more likely they are to get on. We bring Luna home in 2 weeks and I was just wondering if there was any advice for the lead up, the days she’s brought home and after. I definitely know I still need to ensure Jiji is getting just as much, if not more love then he is getting now so he knows he’s still the best boy and loved.
