• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

You can do it! What's the issue here specifically?

Closing this for now. Will try tackling this again at a later date.
If anyone else wants to give this a shot, feel free! 😄

Opened #104 to discuss solutions.
