If you use Projective Simulation in your work (in particular academic publications), the appropriate way to acknowledge the authors who created it is by citing the pertinent publication. If you just need a general reference for projective simulation, the seminal paper is
Hans J. Briegel & Gemma De las Cuevas, Projective simulation for artificial intelligence, Sci. Rep. 2, 400 (2012).
If you are using code that implements specific features or applications, you can find the relevant references inside the docstring; or try the search function.
