No sudden movements, no loud noises, lots of treats and food. I have tamed almost all of my little ferals by approaching slowly when they are eating, or putting the food down and sitting by it, and then attempting to stroke them. I say attempting because they will not approach for a long time, or they run the minute they feel you touching them, but eventually they accept you. Once you can stroke them it is downhill from there. Then after a while you will have to work on getting him/her neutered/spayed. It gives them a much better quality life. Good luck and keep us posted!
