How to apply neovim-nigthly-overlay?

Hello! I’m a newbie in NixOS and I’m trying to get the neovim-nightly-overlay working but I’m getting the error message that this:

          configuration = { pkgs, ... }:

has been removed from homeConfigurations. What do I have to do to fix that?

I found a “similar” post which reported the same error but I’m very clueless what the solution is according to the post. :confused:

Someone from the IRC channel of home-manager helped me and referred me to the changelog which changed that: Appendix E. Release Notes
