You run the keygenme in the release folder, and the objective of a keygenme is that you reverse engineer it by setting breakpoints and/or disassembling it with a debugger such as OllyDbg in order to find out how it validates a password when given a username.
I found the algorithm the program uses to generate a password given a username, and I basically just created a nice little GUI in C++ Win32 to run that algorithm for you.
