 [^omnix]: We use [omnix](https://omnix.page/om/init.html) to initialize this repository template.
 
-[^home-modify]: Executing this step will modify the contents of your `$HOME` directory. You will be [warned before overwriting](https://nix-community.github.io/home-manager/index.html#sec-usage-dotfiles), but not before creating links to newly created configuration files in the nix store. Since home-manager does not currently provide an integrated and automated feature to eliminate the links it creates, be aware that if you would like to reverse this operation, you will need to curate your home directory manually.
-
 ## Details
 
 The configuration repo has `flake.nix` file in the current directory and some `./modules/home/*.nix` files containing the home-manager configuration that you can review. It also has a [justfile](https://github.com/casey/just), which provides a set of recipes analogous to Make targets to interact with the nix flake.
