Yep, Stellarium is good for helping to locate stuff if you're learning the sky and don't have a goto scope or setting circles.

Jupiter and its moons are a great sight also ... rising in the East, they should be at about 15deg elevation by 11pm, 26deg above horizon by midnight, etc. At mag -2.4 it's very bright so hard to miss.
Having some popular/recommedned viewing targets for the month and a basic sky may from might be handy. Easy to get from skymaps.com.
Have attached the download for May:
