Basic care of poinsettias

Basic care of poinsettias

What is the basic care for a poinsettia? I have mine on my desk at the moment, away from direct or even diffused light. I water it when it is dry. It seems happy but I like to have the basic care of a plant. I got this on sale at Lowe's & it didn't have a little care tag. Also, how do they do in the shade outs+ide? They are a perennial, aren't they? Thanks for the help.
