Can you please post the github links for skin helper service, skin widgets, metadata.. I cant seem to find the right version. Or at least say what the latest version is? 
Thank you

Here is the Github link to all of them... They are all maintained by @Angelinas.

Are these going to be added into the repository at some point so they can be auto updated or will we have to manually update them each time?

If you started from scratch with just the repo no skin it will auto update through skin. If you installed the skin then the repo it will not update. The repo should be updated to the latest now.
