What steps do ihave to follow in order to step up Keil IDE to beging programming a digital clock on an STM32F051C8T6 MCU directly connected to my laptop? Also with cube MX?

Directly wired how, exactly?

USB, serial, via a debugger?

Is this chip on some board, or floating in space?

Perhaps try some tutorial videos on YouTube related to Keil, installation, coding, downloading, etc.
