This isn't a thread about how to create a custom config file. If you're here to trying to find that, then go here. This thread is to ask for advice on how to create a clean and simple configuration file. I spend quite a few times trying to find a thread that can solve my issue about writing a simple config file, but I still haven't found it out tho. So, if you have any advice to help, please don't hesitate to share it here! Oops, I forgot to say that it is about config.yml and language (messages) file. Edit 2: I thought I have written enough information, but maybe I didn't. So what I want is to write (not create) a clean, not messy, easy-to-understand config file.
