Front derailleur adjustment
The small chain ring is considered the first gear, so it goes 1-2-3. The derailleur spring pulls the derailleur always towards the smallest chain ring, which makes sense if the cable snaps during a ride: you could still get home without having to walk your bike on hilly terrain. If it was always on the big chain ring, you would need some serious legs depending on your local hills.

Did you ever check a Shimano manual regarding the front derailleur adjustment? They explain very well what you have to do in detailed steps. But if you can't get it right using the mentioned Park Tool tutorial, i would really recommend visiting the LBS.

What i am missing in the Park Tool tutorial is the step where you have to loosen the inner wire. This should be "Step 0". The wire has to be loosened while adjusting height or rotation of the derailleur.
