Suggestion: Create contribution guide
Most projects will include a CONTRIBUTING.md file (like the README) in the root directory of the project to help define certain style guidelines and principles that a project adheres to. This is an exmaple, which is used by the Cockatrice project. I noticed that the most recent commit made some changes to the code to start making a consistent style (tabs->spaces, apostrophe-surrounded strings, etc.), so I figured that now may be a good time to establish your preferred style so others can use it as well.
That's not a bad idea. I'll copy up my eslint rules and link to the Google Javascript Style recommendations when I have a chance. :)
I now have an .eslintrc, so hopefully I can start to enforce it with TravisCI soon.
Cool, that's a great plan! That would be a different "issue" though?
That will be, but the .eslintrc file is good for contributing. :)
