Wireless programming

Using Arduino Networking, Protocols, and Devices
1

Hi,
I need to program an Arduino UNO wirelessly through some protocol (can be wifi, bluetooth anything).
I wanted to start from the basics so for starters, if anyone could tell me how the arduino is really programmed, it would be helpful. Also, what other requirements do i have to implement such a system.
I have a nRf24l01+ module which i can use if possible.

Thanks

Don't you know how you are doing it, today?
