How connect arduino pro mini to 0.96" SPI Serial 128X64 OLED Display

Hi all

I searched the internet, but I found nothing concrete about how it connects properly to arduino pro mini.
OLED display pins in order:

GND, VCC, D0, D1, RES, DC, CS

Thank you very much!

          (B) use different pins with xxx_SW_I2C()
          
          
Q: My display has a pin labled as "A0" (or "RS"). How to connect this pin?
          A: There are different names for the "data/command" pin. In U8g2 only the name
          "dc" is used. On the display side it might be also called "A0", "RS", "CD".
          See also the next question.
          
          
Q: My display has pins labled as "D0" and "D1". What is the interface and how 
          to connect these pins?
          A: This is probably a SSD1306 OLED. The meaning of the D0 and D1 pin depends
          on the configuration of the SSD1306. D0 is the clock line and D1 is the data line.
          
          
Q: For HW SPI no pin numbers are required in the constructor. But which are
          the pin numbers for wiring?
          A: This depends on your board. For some official boards, this is listed here:
          https://www.arduino.cc/en/Reference/SPI
          You need to connect MOSI (data) and SCK (clock) pins of your board with the
          corresponding pins with your display.
          All U8g2 software emulated SPI constructors look like this:
          U8G2_..._4W_SW_SPI u8g2(U8G2_R0, clock, data, cs, dc, reset);
          All U8g2 hardware SPI constructors look like this:
