 The Pi needs a [2.5 Amp power source](https://www.raspberrypi.org/documentation/hardware/raspberrypi/power/README.md). Most modern USB chargers you'll have laying around will work, but an older/cheaper one may not.

 ## Common issues

Double-check that you're using [a blessed SD card](http://elinux.org/RPi_SD_cards), and try flashing the image again.
