ESLint Reset - A starter .eslintrc file that resets all rules to off and includes a description of what each rule does. From here, enable the rules that you care about by changing the 0 to a 1 or 2. 1 means warning (will not affect exit code) and 2 means error (will affect exit code).

# You will learn why `make` is so great, and why, despite its "weird" syntax,

# Pick and choose what you want, as all models don't NEED to be tested at this depth.
