May I add : take your time. I advise to take the manual, read a chapter, do some practical exercises on the unit to make sure you understood everything, then do the same for the following one.
Reading @Merlin’s famous “Thoughts On OT” is a fabulous experience when you struggle to see how OT different parts can be used in a coherent workflow.
But skipping the manual is just not an option.
Be patient, the reward is immense.
