I of course meant with the review comment if your repo can change to the appveyor.yml template 😄

Disabled the Stale bot and changed the labels. Also talked to Cory who'll get back to this as soon as he can.

I have permission on the repository, and I will see if I can get this resource in good shape for next Community call where we'll be able to reconsider this.

[gaelcolas]

As announced during the last community call, we'd love to have this as part of dsccommunity. @corydwood gave me permissions to the repo and I'll try to get this re-homed when we transfer to the new GitHub organisation in a few weeks.
