NPM version is not up to date
@kbrsh can you please fix this? I'm missing the cards component from the NPM package. CDN is also not updated. I'm guessing you have to up the version tag.
Edit: The Github version is not even up to date to the version on your website (https://kbrsh.github.io/wing/#guide). See the wing.css comparison screenshot below. Left hand side is the card styles pulled from github. Right hand side is the card styles live on your demo website.

How do we use the latest bits? With more than 200 commits since last release?
I'll have to update the NPM version, but for now you can use the latest GitHub version by either downloading the files directly or having this in your package.json:
"dependencies": {
"package": "github:kbrsh/wing"
}
The version hasn't been updated still, and the documentation needs updating as well, any eta?
