How to power PSOC 5LP from boost converter

I have the CY8CKIT-050 PSOC 5LP development kit, and I have read that I can power my chip though boost converter (Page 16, last line), but I don't find any place where get information about how to configure boost converter to power the chip. I tried just to disconnect the usb supply but as I expected, the boost converter didn't power the PSOC.

Incidentally, I don't have any components connected to the PSOC, just the power supply to the boost converter and the USB connected to my laptop.
