Do you have tutorials you recommend?
Imagine your derailleur is an elevator, which hangs from cable. For safety there are switches at the top and bottom of the shaft to keep it from hitting the end. These can also be set to stop the elevator to stop in the right place at the top and bottom floors, but it's really the cable that determines the height of the elevator at each floor.

Likewise, the derailleur limits prevent overshifting beyond the chainrings, but the cage position depends on the cable. However on the innermost chainring the cable is slack so the inner limit also sets the cage for low, much as the lower elevator might set the basement stop position.

I hope that helps.

I can't suggest any single tutorial, but I always suggest watching a few. Sometimes something not covered well on one becomes clear on the second. The point is you want to have a sense of the job in your head, rather than simply following steps by rote.
