Bit stuck on how to get started with postcss. Which on one hand validates the value in this PR, but on the other hand is quite frustrating. Grateful for any hints @tylerkrupicka

Thanks for taking a look at this!

Not 100% sure, would have to take a look later. Some ideas off the top of my head:

You're using a newer version of PostCSS that just came out, I haven't used it yet. I think plugins are a little different so maybe downgrading might help?

Maybe a different node version will help? I think I use 12.x.

I'd look at the PostCSS docs for using the config.js format vs config.json and see if something changed.

Thanks again!
