Layer 2 mess

I just recently started playing with layer 2 (Arbitrum).

It seems really not intuitive and too complex for the normal user. I am tech savy and found it too complicated. from L1 to L2 it is fine, but from L2 to L2, it needs to be documented somewhere. For example. I wanted to transfer from Arbitrum to dYdX to save on deposit fees. And realized it is no longer possible. Was possible before it seems on Orbiter finance, tutorial I followed: https://www.youtube.com/watch?v=Fsp7rCXBqgg

Rant over, let's do better documentation!
