You should get on line and print out a fingering chart and study it. Then when you are ready buy some books on how to play the flute.
A flute gives out a soothing, welcome and resonate sound. One of its masters is Jean-Pierre Rampal, a French flautist of historical times. A solid basis for the opening student is to put exceptional stress on developing the technique.
To start with there are some exercises to be performed. Initially you should know how to blow producing a steady sound on the flute and keeping the corners of the lips firm. You need to control the angle of blowing the air in a steady sound and keeping the correct angle that produces proper sound. Place the mouth pipe part of the flute on your closed lips. Make sure that the hole touches your lips equally. Rotate the mouthpiece down and away. Blow the candle for exercising to get a steady pitch. Get the flute in playing position. Push and hold down the three top keys with the left hand plus the thumb key & blow producing a second line G on the treble clef. Take a deep breath and maintain the sound.

If you have never played before, I would first try just to make a clear sound with only the headjoint of your flute; it is more difficult for you to make a clear sound with the entire flute. I would fit the headjoint so your lips are centered and your bottom lip covers part of the hole, then blow. Ideally, half your air should go into the flute and the other half over the top of the flute. When you can sustain a clear sound, then try with the entire flute. It is easiest to start on a Bb. It is important to have good breath support to play the flute.
The bottom of your bottom lip should be touching the hole for your mouth. Then learn where your fingers go. Check out or buy some books to help. The flute is a little challenging but not as difficult to play as those instruments with a reed. The best of luck.
