Can you embed the link to the Power Management chapter
:doc:`Power Management<../prog_guide/power_man>`

I think in this over all section needs a lot more explanation like what are valid training flags and how to get thresholds ect.

Also you could highlight the commands it looks better:      ``training_flag``
