It looks like the plugin itself is missing the download capabilities. Please update and notify once this is fixed

Hey @jthegedus, I've just pushed those changes up and also refactored the scripts to better match the current asdf template

It looks like the plugin itself is missing the download capabilities. Please update and notify once this is fixed

Let me know if there is anything else I can do to help
