 ### Note on secrets management
 
-Secrets are managed using [git-crypt](https://github.com/AGWA/git-crypt). To unlock the repo, use `git-crypt unlock [path to key file]`. git-crypt will transparently encrypt/decrypt files stored in `modules/secrets` going forward, but you'll need this key file on all hosts that are using secrets.
+Secrets are managed using [transcrypt](https://github.com/elasticdog/transcrypt). To unlock the repo, use `transcrypt -c [cipher] -p '[password]'`. Transcrypt will transparently encrypt/decrypt files stored in `modules/nixos/secrets` going forward. You can get the cipher and password from a host with transcrypt already configured by running `transcrypt --display`.
 
 > [!NOTE]
 > This is a poor man's secret management solution. If you use this, your secrets will be world-readable in the `/nix/store/`.

 ## About this repository
 
-### Layout
+This config uses the [Snowfall lib](https://snowfall.org/), along with some default options and settings for common software. It features:
-
-This config uses a custom templating system built off of the [Auxolotl system templates](https://git.auxolotl.org/auxolotl/templates).
-- Flakes are the entrypoint, via `flake.nix`. This is where Flake inputs and Flake-specific options get defined.
-- Hosts are defined in the `hosts` folder.
-- Modules are defined in `modules`. All of these files are automatically imported (except home-manager modules). You simply enable the ones you want to use, and disable the ones you don't. For example, to install Flatpak support, set `aux.system.ui.flatpak.enable = true;`.
-    - After adding a new module, make sure to `git add` it before running `nixos-rebuild`.
-- Home-manager configs live in the `users/` folders.

-### Features
