@benlowry I just forked it to keep Skeleton alive. There are 48 outstanding PRs and none of the files have been updated in 2 years.

Please feel free to come to mine and do a PR. I'm going to start maintaining it and looking for people to help me too. Are you interested? If not, just ping me your PR and I'll test and push it out within 48 hours.

Take care @benlowry
