Arduino and NRF24L01

I'm sorry I have a question about programming Arduino with NrF24L01 module, I want send a data from sensors Pressure Gauge and Infrared, I want to send the data that been received and transfer it from transmitter to receiver (both are NRF24L01 module) and from the receiver the data will disolayed on LCD, the data that will be disay is Height and Weight, thank you

and your question is...?

The rf24 tutorial by Robin2 is a good place to start.

How to write the program ? And I use the level shifter beetween Arduino Nano and NRF24L01

The programs are in the link that @groundFungus gave you.

And I use the level shifter beetween Arduino Nano and NRF24L01

The nRF24 must not have more than 3.6v on its Vcc pin but it can work with 5v on the other pins so no level-shifter is required.
