Questions about the files mentioned in this project

[BlackPeonyFish]

Dear author, I am a graduate student, and I want to use parallel genetic algorithm to train my racing AI, so I read your article. I have to say that your article is very hardcore. As a novice, I can only barely understand your "get started" part and implement the running of the test file. But then, you asked me to read the Tutorial: TMRL as a Python library part, which made me confused. Please forgive my stupidity, but you tried to teach me to write a py file, but even if I learned how to write this file, which folder should I put it in, and what file should I run? In addition, you also provided a large number of script files in the directory, such as custom, tools, etc. Where should these files be placed, and which file should I run? I have no answer to these questions. I hope you can provide more detailed explanations for beginners like me, thank you very much! !
