Yea, there's been quite a few posts on the subject. I tried it first time last winter with a few common C. Annuums just to test the waters. I made enough mistakes to probably try this winter with another plant or two. They better be darn special plants cause its a pain.
There are versions to consider: 1) full growing, just keep the plant under quality lights, keep watering and feeding. 2) induce-semi dormancy. 3) bonsai / bonchi mini plant.
I did the semi-dormancy thing: Before first frost, dig up plant. Hose it down, roots and all. Severely chop the top leaving 8-10 inches of trunk. Trim the roots so it is a ball smaller than your fist. Put it in a 1-quart plastic container in STERILE medium. Water it one time. Put it in a room where it is 50-F and gets only a little light. Around February, think about breaking dormancy by watering, increasing warmth and light. Consider a pot up in new premium growing mix around March. (DISCLAIMER: This is NOT guaranteed--the farther you get from Texas, So Cal or Florida, the harder it will be!)
OR---Consider the Bonchi procedure thingie. That might be a good way to go for one special plant. Good luck....
