Nice and simple.

If you put "code" tags around your code it will look better - plus, given that this is in Python then the tabs/spaces at the start of line are crucial for anyone trying to copy/paste.
Might also add that it is python (could give an example file name) and how you start running it - for the people who are less confident in getting things up and running.

Yes, I will fix it. so I will make a service to run the script and config file (server and player settings)

you also need to install
