Can't you just read what it means? Note: The column is the cost of upgrade, assuming that you have all the resources needed, but don't want to use the  Command Center. Buying the upgrade does it instantly, even if  Command Center  is busy building something else. If you don't have enough  Incendiary Cores, add 25 to the cost.
