[racket] classes and objects

Could anyone explain me how to create objectsand their instances?
I've read of course the racket guide and reference but the examples I foundthere are (for me) completely useless:
I'm not interested in how to create class hierarchies. The only thing I want toknow is
how to create a class and how to create for example 3 instances of the class. I’dlike to know what exactly the “size” parameter is and if I have to use it.
Thanks in advance
