 This module provides a subset of features provided by the system-wide sops-nix since features like the creation of the ramfs and changing the owner of the secrets are not available for non-root users.
 
 Instead of running as an activation script, sops-nix runs as a systemd user service called `sops-nix.service`.
-And instead of decrypting to `/run/secrets`, the secrets are decrypted to `$XDG_RUNTIME_DIR/secrets` that is located on a tmpfs or similar non-persistent filesystem.
+And instead of decrypting to `/run/secrets`, the secrets are stored decrypted to `$XDG_RUNTIME_DIR/secrets` that is located on a tmpfs or similar non-persistent filesystem. Additionally secrets are symlinked to the user home-directory in the `.secrets`-directory which is used as reference 
+for the `.path` value in nix. Because of that, the home-manager option `home.homeDirectory` is used to determinate the home-directory on evaluation, 
+this has to be set manually if home-manager is used standalone or on non NixOS systems.
 
 Depending on whether you use home-manager system-wide or using a home.nix, you have to import it in a different way.
