 VDD should be connected to +3.3V and VSS should be connected to ground. These nets are often used in a schematic, so to avoid drawing nets across the whole schematic you can add power ports. All power ports are global in your design, which means that all power ports of the same kind is connected to each other.

 The NRST pin is an active low (0) input used to reset the MCU.
 There is an internal pull-up resistor keeping the pin high (allowing the MCU to run). For more info on what a pull-up resistor is, search the internet for ”Pull-up resistor”.
