Welcome to your first Phalaenopsis orchid then catweazel. These should get dappled light, no direct sun if possible, and do well in a windowsill. It looks like its in a bark mix from the photo. This should mean watering about 1 time per week. Just stick a chopstick or similar into the media and pull it out. If it's damp/wet, you can wait a few days to water. I fertilize every week with a 1/4 of the recommended fertilizer dose. I'm giving you the link below to caring for Phals. It's a lot of information, but remarkably helpful and detailed throughout. Good Luck, great orchid!
