Interfacing external ADC with arduino through SPI

Hi all, As the title suggests I am trying to interface an arduino nano with a MAXIM1112 multi channel, serial 8- bit ADC. Due to a constraint in my project I have to use this chip instead of the nano's internal ADC. When interfacing modules with Arduino in the past I have mostly used example code and provided libraries. However, from my research, no example code exists for this chip. I know the answer lies in the datasheet for this chip but I do not know where to start or what I am looking for. Any help would be greatly appreciated!
