How do you feel about article 2 and 3 explaining the stuff that was explained in article 1 less and less? In order to avoid repetition.
It's ok for things like actions. For example, if in article 1 you already showed steps on how to instance and add script to it then in article 2 you can just say "now instance player.tscn to the main node then attach a new script called 'player script'.."
For coding though, as I am a bit slow, I need to be reminded on where to place new code, usually when hopping between functions, Like "in ready() ..add this ..#newcode below #thiscode then in physic_process() add this #anothernewcode ..between.. #thiscode and #thatcode".
