For getting started, I would recommend you to have look at the following pages:

• Infocenter: nRF5 Getting Started
• The nRF51-DK User Guide: Can be useful even though you don't have the DK itself
• The "Getting Started" section for the tutorials here on devzone.

By " flash the softdevice before flashing ble_app_uart", I mean program the softdevice before the ble_app_uart.
