Confused as to which SDK to install for nrf52-DK.

I ordered nrf52-dk.

I am trying to install the SDK using nrf Connect Desktop using  the option below: 

Getting Started Assistant
Guide to set up the nRF Connect SDK

I see the message below:

"The nRF Connect SDK supports nRF53 and nRF91 Series devices. For nRF51 and nRF52 Series devices, we recommend using the nRF5 SDK instead. See our Software development Getting Started Guides for more information."

But on the website it says otherwise.

"nRF Connect is designed to be used in conjunction with the nRF51, nRF52 and nRF53 Series development kits and dongles, and nRF91 Series development kits. nRF Connect will automatically detect which kit is connected to your computer and upload the needed firmware. "

What should I do as I am using the nRF52-DK
