@mbuchetics Thanks! Mind giving an example on how they can integrate it and I'd be happy to add it to the readme?

I simply added
github "iwasrobbed/Down" ~> 0.3
to my Cartfile and ran carthage update (see https://github.com/Carthage/Carthage).

You can omit the version and just put
github "iwasrobbed/Down"
This is how most frameworks are describing it in their readme (however, I think it is good practice to specify a version).

Other than that you just have to make sure that your Xcode schemes are shared (https://github.com/Carthage/Carthage#share-your-xcode-schemes). But you are already doing that, so it just works out of the box 👍
