Has this issue been solved or can i still contribute to it?

[jsoref]

No. In theory you could try to write a PR offering such content.

I tend not to make PRs for things until I get an indication from GitHub staff that they'll accept it. (But, that's a personal choice wrt managing my resources.)

It's okay now but you can still help by cording easy and quick understanding

@jsoref Thanks so much for opening an issue! I'll triage this for the team to take a look :eyes:

Thanks for opening an issue @jsoref! I've looked at this one with the team and we think it makes the most sense to just add a new section below "Archiving a repository" called "Unarchiving a repository." Several of the steps can just be reusables from the Archiving section.

You or anyone else is welcome to open a PR with this update!
