Power Setup for MDF Track?

Right now I am running SSD track where the power supply is simple... hook this up to the rest of the track and things work.
However, I am not sure of the power setup for a homemade routed MDF track works.
I am starting from the very beginning and have no idea how to set this up.
Has anyone written up the entire process of creating the power setup for an MDF track?
• Track power to the braids
• What power supply to use
• Controller power (plus all the negative/positive controller... blah blah blah)
• and anything else I do not know about...
Thanks for the help,
Ryan
