Cannot use the IR library demos

hello everyone I recently got my Uno and as a head start project I wanted to make this but when I open the IRrecvdemo example and try to upload it get this error

""C:\Program Files (x86)\Arduino\libraries\RobotIRremote\src\IRremoteTools.cpp:5:16: error: 'TKD2' was not declared in this scope

int RECV_PIN = TKD2; // the pin the IR receiver is connected to

^

Multiple libraries were found for "IRremote.h" Used: C:\Program Files (x86)\Arduino\libraries\RobotIRremote Not used: F:\Documents\Arduino\libraries\Arduino-IRremote-master exit status 1 Error compiling for board Arduino/Genuino Uno.""

Not used: F:\Documents\Arduino\libraries\Arduino-IRremote-master

Rename that directory to "IRremote" and re-start the IDE.
