Restore .nimble to update package
The README of both [nimble](https://github.com/nim-lang/nimble#releasing-a-new-version) and [packages](https://github.com/nim-lang/packages#releasing-a-new-package-version) says to edit "your .nimble" and I assume, this file is created at the initial `nim publish`

In case that is correct: How to restore that data, once deleted?
There is no documentation, that I can find. 

Great day 🌞
