Hi,
If you already have Keil MDK5 installed, you only need the SDK and the nRF5x Command line tools to get started. More details about our recommended tools can be found on this page.
The latest SDK supporting the nRF51 series is SDK v12.2.0, which can be downloaded from here. Details on how to get started with development, can be found in the Getting Started documentation of the SDK. A softdevice is a software stack that implement the specifications of Bluetooth Low Energy or ANT. If you want to run one of the BLE or ANT examples in the SDK, you need to flash the supported softdevice first.
You can find some great tutorials that will help you get started in the tutorials section here at DevZone.
Good luck!
Best regards,
Jørgen
