Need help in choosing a library for wireless and coding

I have the following transmitter and receiver. I would like to know if there is a simple library (like the library for LCD) to program them. Attached is the datasheet. Can someone point me to a good source to getting started with them.

For OOK (On/Off Keying) you can use the VirtualWire library fro communications.
