This repository should be archived and the README updated

[bmitc]

• This repository should be archived to make it read only.
• The README should be updated to say it is no longer active and to point to https://github.com/erlef/docker-elixir.

Any possibility that anyone here has permissions to properly archive this repository? If not, I'll close this issue in one week. See also #149.

Closing as repository is unmaintained.

I don't have permissions, but perhaps a PR that makes the changes to the README would be easier for someone who does. I know for some of my older repos, when someone did the work and I just had to merge, it was more likely to happen than if someone was asking me to make changes.
