source code for interfacign with rf transceiver

hello i m a student working a project that requires me to interface an arduino pro mini with an rf transceiver nRF24l0+, i bought the breakout board from sparkfun.

i have done the physical connections part alrdy, but im having a lot of trouble and confusions when starting with the source code. is there anyone who has a sample source code for this? i m trying to interface them trough SPI method.

is there any other way of interfacing this?

please help me... any amount of information or links would be very helpful... thank you very much..
