You will find the latest information about MySensors here:
Connecting Radio Module
Wire things up
Use the dupont cables and follow the table below to connect the nRF24L01 to your Arduino board.
Note: Arduino Pro Mini does not have 3.3V output. You will have to use a power regulator 5V->3.3V (see purchase guide). The radio chip does not like 5V!
For more information about the radio chip, have a look here:

For a more comprehensive guide how to connect radio chip (use RF24 library setup):
