Wow, it's a beauty, Lisa. Needs a new pot, though. Cyms are terrestrial orchids so you can pot it in regular potting soil with some extra perlite mixed in. A couple of mine were potted in chunks of coco fiber, which also seems to work well if you can get some. I'd still mix it with some potting soil.
Water generously and fertilize like you would any other container plant. It would probably do well with some morning sun, afternoon shade, or if you have a spot under a tree with dappled shade that would go well, too.
They like some chill in winter but can't take freezing weather, so you can leave it out in fall until the nights fall below about 40deg. then bring it in to somewhere cool, but not too cold. It will keep its leaves all winter, so somewhere with a window or at least some natural light indoors is good.
