trying to run the peripheral heart rate example on the nrf52840 DK Not building

Hi apparently the examples are not working out of the box. I do not see any documentaiton on what has to be done for them to work. Can you advise me on what i shoud do to build and example like ble_app_hrs_pca10056_s140 on the segger embedded studio? I was expecting this to be as the STM32 examples, download  build flash.
