This example shows one common way of holding a guitar pick between the thumb and index finger. You don't have to hold your pick exactly like I do. This is just a good place to start from. Everyone's hands are different so feel free to modify this so that you're comfortable. This video also shows picking technique examples of strumming, picking chords and shredding.
Guitar pick selection is also very important. I find that thicker guitar picks are more effective in producing a good heavy metal sound. I use Fender heavy's and Dunlop Tortex Standard Picks 1.14mm. You may want to experiment with different thicknesses according to your playing style. If you're just starting out, I would strongly suggest you use the type of pick shown here. There are many different shapes and sizes for guitar pick, but these are the most common and if you're on stage and loose your guitar pick, this is the type of guitar pick that will most likely be handed to you by a helpful musician. The stage is not where you want something that you're not used to using.
