Is it true that if you assign officers to duties that your ship will begin to generate raw dilithium?


Additionally, I am relatively new to the game...a level 21 Commander...and I find the game intoxicatingly addictive but frustratingly and intensely details/designed so this whole duty officer/assignment thing makes me more confused to understand it.

As a visual learner, is there a video out there (on youtube) that walks one through this process?
