+## Important Notes
+
+### Avoiding Configuration Conflicts
+
+External modules should generally **not** override settings that are already defined by the host type modules (like `nix-lxc`). The host type already configures:
+- SSH settings
+- Basic services
+- Networking
+
+Your external module should focus on:
+- Application-specific packages
+- Custom services unique to your application
+- Application configuration files
+
+If you need to override host type settings, use `lib.mkForce`:
+
+```nix
+services.openssh.settings.PermitRootLogin = lib.mkForce "no";
+```
+
 ## Deployment
 
 After updating the configuration:
 
 ```bash
 cd /path/to/nixos-systems
-# Update the rev in inventory.nix
-nix flake lock --update-input usda-dash-config  # If using flake input
-# Or just update the rev in the fetchGit call
+# Update the rev in inventory.nix to the new commit hash
+# Nix will automatically fetch the new version
+nix flake check  # Verify the configuration
 ./deploy usda-dash
 ```
+
+To force Nix to re-fetch (if you've updated the same commit):
+```bash
+rm -rf ~/.cache/nix/gitv3/*
+nix flake check --refresh
+```
