Add example projects using kcd-scripts

[AndersDJohnson]

It's be valuable to have a couple reference usages outside of kcd-scripts itself, since the dogfooded setup is a bit different than most consumers.

This would be great! Would you like to make a pull request to get such a list started? Could be in an other/USERS.md file that's linked to in the README :)

[AndersDJohnson]

@kentcdodds I was hoping you could refer me to some existing projects.

You can see a list on the Dependants page. Maybe we could just link to that?

I'd rather just add a link to the dependents page I think.
