Old Fuel Bleed

My car has been sitting around for over a year now and has not been routinely started and driven. I want to get it back on the road. I read somewhere that I should bleed out the old fuel as it maybe varnish and could cause problems down the line. Should I be worried about this? If so, what is the technique on bleeding out the fuel? I am a novice in car mechanics, handy and willing to learn.
