You're in luck. There's an article for that: http://learn.adafruit.com/drive-a-16x2- ... i/overview
Note that the article talks about standard LCD's, but the same instructions work great with the 823 OLED. Just don't wire anything for pins 3, 15, and 16. They have to do with contrast and backlight, which are N/A for OLEDs.
Also, be aware that the 823 OLED is only mostly HD44780 compatible, and it doesn't really play nice with I2C or SPI backpacks, just in case you were eyeing one of those to reduce the GPIOs that the display will take up.
