Feel free to contribute at any time! As a novice, I enjoy learning from others, and I'd like to keep this project afloat.
Any issues go in the Issues tab. Make sure to clearly state what the problem is. Examples:
Good: I've gathered $150, purchased a coffee machine, and automated it. No money is being generated. I get this error repeatedly in my console: "blah blah error." Can someone help me?
Bad: My auto coffees aren't working! Fix it!
An error message will let people know where it's happening, but a single sentence complaint is very vague.
I'll be very glad to look at any and all pull requests made. A new feature might take a bit to be approved, since it has to be balanced. A style enhancement is welcome, but not as high on the priority list right now. The stage the game is in right now is mainly unstyled, but needs more features.
Suggestions are always welcome because I can't churn out ideas all the time. Simply create an issue and tell everyone how it could be implemented, what it does, and how it could be balanced. Remember, even if I don't see your issue, someone else might, and make a pull request, which I will definitely see.
Contributing doesn't mean just writing code just as the Open Source Guide declares. Writing a wiki can help newcomers. Don't be afraid to contribute.
Above all, follow the Contributor Covenant and keep a civil tongue. Think before you post something that could spark an argument.
