The process involves physically connecting the RTC to the Raspberry Pi, configuring the Pi through the terminal, and modifying files to use the RTC for timekeeping. The tutorial provides step-by-step instructions and includes commands to enter in the terminal. The end result is a Raspberry Pi configured to use the RTC for accurate timekeeping.
