I'd like to use an ATMega328P for my project, I hope to do it without the Arduino board.

I know with the Arduino IDE and an Arduino board I can program the microcontroller. However, would it be possible once I've programmed and debugged the program with Arduino IDE + Arduino board, to take away the microcontroller from the Arduino board and to use the ATMega328P separately, without the board?

If yes, what additional configurations I should do the ATMega328P to work correctly on the breadboard?
