Hi and welcome to Orchidboard
I'm guessing you most likely have a Phalaenopsis which is the type we commonly see in stores. If you could possibly show us a picture of what you have, we can give the correct advice. Going on the assumption that you have a phal, they like indirect, filtered lighting.
Here's a sheet to help you:

We have lots of folks here just starting out in orchids. Many of them were also a little tentative about getting involved in our forum but they've all become familiar with the forum and they are an asset to our community. I'm sure you'll feel just as comfortable in a short time
If you have questions, feel free to ask
