 # secrets
 
-`secrets/default.nix` declares the secrets exposed at evaluation time.
-these are defined *outside* git by writing the actual values to `secrets/local.nix`.
-
-*don't* check in the local.nix file. use `git update-index --assume-unchanged secrets/local.nix` to prevent it from ever being added.
-but after that you can set them to their real value and run `git update-index --assume-unchanged secrets/*`
+i use [sops](https://github.com/Mic92/sops-nix) for secrets.
+see `modules/universal/secrets.nix` for some tips.
 
 ## building images
 
 to build a distributable image (GPT-formatted image with rootfs and /boot partition):
 ```sh
-nix build .#imgs.lappy
+nix build ./#imgs.lappy
 ```
 this can then be `dd`'d onto a disk and directly booted from a EFI system.
-there's some post-processing to do before running a rebuild on the deployed system (e.g. change fstab UUIDs)
