I did that here:http://www.gammon.com.au/forum/?id=11637You don't need a crystal if you don't mind running at 8 MHz.You can have a reset button if you want. If you want SPI (for ICSP programming) you can break out those pins.Diagram:
I would like to ask you about the capacitors near the crystal. Which are their description ?

Alternatively, use a 3-terminal ceramic resonator instead of a crystal (like the Arduino Uno does), which gives you a slightly less accurate frequency (usually +/- 0.5%) but has the capacitors built-in.
