 # USDA Dashboard External System Module
 # ============================================================================
 # External system configuration for usda-dash
-# This module can be referenced from nixos-systems/inventory.nix using:
-#
-#   nix-lxc = {
-#     devices = {
-#       "usda-dash" = builtins.fetchGit {
-#         url = "https://git.factory.uga.edu/MODEL/usda-dash-config.git";

-#         submodules = true;  # REQUIRED for usda-vision submodule
-#       };
-#     };
-#   };
-#
-# IMPORTANT: For LXC containers running Docker, the Proxmox LXC must be configured with:
-#   - Features: nesting=1, keyctl=1
-#   - Unprivileged: no (or privileged: yes)
-# Edit the container config in Proxmox: /etc/pve/lxc/<VMID>.conf
-# Add: features: nesting=1,keyctl=1
 #
 # USAGE FROM ATHENIX:
 #
-# 1. Add usda-vision as a flake input in athenix/flake.nix:
+# 1. Add required flake inputs in athenix/flake.nix:
 #
-#   inputs.usda-vision = {
-#     url = "path:/path/to/usda-dash-config/usda-vision";
-#     inputs.nixpkgs.follows = "nixpkgs";
+#   inputs = {
+#     usda-vision = {
+#       url = "git+https://git.factory.uga.edu/MODEL/usda-vision.git";

+#       url = "github:yaxitech/ragenix";
+#       inputs.nixpkgs.follows = "nixpkgs";
+#     };
 #   };
 #
-# 2. In inventory.nix, pass the usda-vision packages and ragenix-managed secrets:
+# 2. Pass inputs to modules via specialArgs:
 #
-#   imports = [
-#     (import /path/to/usda-dash-config/default.nix {
-#       usda-vision-packages = inputs.usda-vision.packages.${system};
-#       envFile = config.age.secrets.usda-vision-env.path;
-#       azureEnvFile = config.age.secrets.usda-vision-azure-env.path;
-#     })

+#     modules = [
+#       ./path/to/usda-dash-config/default.nix
+#     ];
+#   };
+#
+# 3. Configure secrets in your athenix configuration:
+#
+#   age.secrets.usda-vision-env = {
+#     file = ./secrets/usda-vision/env.age;
+#   };
