Bringing in a feral, need advise

Hi, I'm new here. I want to try bring a feral kitten, about 6 months old, inside.
We have been feeding her for the last 4 months.
I was able to trap her yesterday and a rescuer took her to a shelter to be neutered today. I have two 14 year old indoor only cats. 
I would appreciate any advise on making this work. Thanks

Thank you so much for helping these kitties.

My own tip:  patience.  And proceed slooowwwllly.  Well worth it.

Good luck and let us know how it goes.
