Hello everyone. I just bought a small (~3-4") hindu rope the other day and am looking for some tips on how to eventually get a long, full plant with multiple vines. Right now, it's got one little vine, and I was wondering if it will eventually grow more vines on its own or will I have to take cuttings and plant them in the same pot? If so, how much should I let it grow before I start taking cuttings?

One other thing I've been wondering about is lighting. I only have south-facing windows in my apartment so I worry about the light being too intense. Is it ok to put the plant in the window sill or should I place it further away? I want to make sure it's getting enough light to grow but I don't want to burn it either. Any help is appreciated!

Here's a photo of the plant with my hand for scale:
