The following was summarized from the BBC Sports Academy:

Level 1: * swim with body close to surface, hips and legs above shoulders * keep face in water * kick all the time * legs create buoyancy and balance * use long fast kicks * count to 6 for kicking rhythm * knees should be slightly bent * arms create thrust * minimize splash by entering hand thumb-first * increase speed by bending elbow and pushing hand towards feet * follow through until full cycle to conserve power * outside of water, let the arm relax * breathe regularly * turn head smoothly leaving one side in the water
