Any updates on this?
At first, it throws this warning, but then it seems to stabilize.

The package owner's last action on Github was on 12 September 2017, and even than there was just that one day that month. So basically, no activities detected since end of August.

Okay guys, instead of posting a useless "+1" — for which Github introduced the thumb-up icons to prevent spamming the discussion — have a look at the top level project README that I updated today. Somebody has to actually DO the work. Volunteers wanted and welcome.

@lll000111 It is not clear how to fix the error, could give a link to a specific line in the README?

Fixed as well in #636
