That's all there is to it! It seems intimidating, but with some practice and slow memorization, you should start getting somewhat fluent with you cube. If you want to go beyond this, here are some tips to learning how to solve the cube without this guide and with better times:

• Don't rush yourself into memorizing algorithms. Have someone mix up your cube, or if you're brave, mix it up yourself. Then use this guide to solve the cube. Eventually, you will be performing the algorithms by feel or sight, without even thinking of the letters. If you try and rush into learning the algorithms, you'll never actually be fluent with the cube, because you are just trying to remember letters.
• Don't worry about rushing to get the cube done. Sure people would be amazed if you could solve the cube faster than they can mess it up, but hey, I can't even solve it that fast, so don't be discouraged. The Rubik's cube freaks, excuse me, enthusiasts use specially made cubes at competitions that you can practically turn with just one finger. If you're concerned with time, just don't worry about it when you're solving the cube. You'll find out that you get better times when you just concentrate on solving the cube.
• Find shortcuts and other things that work for you. The reason that I was a little vague on some of the steps was so that you could find what works for you. Every cube-solver uses their own customized technique, so this is just a template for that. On my links page, there are some other methods that other cube-solvers use, that may be more difficult. Be sure to customize these faster methods for what works for you.
  

Happy cubing!
