I am sure you know to put batteries in the camera, power it on and then point and click to take your picture. I would definitely recommend before you take any pictures to look over your user manual and check out the features you have on your camera. For example, I have a night, landscape, sport, and portrait setting for taking pictures. If I want to take a picture of my cute dogs snuggling together on the couch, I put it on the portrait setting and snap away. If I want to take an action shot of my son skate boarding down the road, I put it on the sport setting. You also need to set the quality of the shots on your camera. The higher quality the picture, the more memory it takes, so less pictures can be stored in your camera. And of course vice versa, the lower the quality more can be stored. I personally don't see a problem with high quality shots. If you download them regularly to your pc, you won't have a storage problem.
Don't forget about holding the camera correctly and making sure the optics are clean. Digital cameras are getting smaller by the day. You don't want to take shots of your cousins wedding and then realize you have several pictures of your finger. Make sure you keep your fingers away from the lens with your index finger on the shutter button and your thumb on the back to hold the camera steady. Also, it is really easy to get finger prints on your camera lens. This makes your pictures come out fuzzy. Make sure you clean your lens regularly with the correct cloth and solution.
