+## Adding New Systems
+
+To add a new system configuration to the infrastructure:
+
+1. **Create the configuration file** in `nix-system-configs/modules/system/`:
+   ```bash
+   cp nix-system-configs/modules/system/blank_system_USE_THIS_AS_COPY.nix \
+      nix-system-configs/modules/system/your-new-system.nix
+   ```
+
+2. **Edit the configuration** to set your system's unique properties:
+   ```nix
+   config = {
+     local.hostname = "nixos-your-system";
+     local.username = "yourusername";
+     local.userDescription = "Your System Description";
+     local.address = "10.XXX.XXX.XXX";  # Choose an available IP
+     
+     system.stateVersion = "25.11";
+   };
+   ```
+
+3. **Register in `flake.nix`** to make it available for builds:
+   ```nix
+   nixosConfigurations = {
+     # ...existing configurations...
+     
+     "nixos-your-system" = nixpkgs.lib.nixosSystem {
+       inherit system;
+       modules = [ ./nix-system-configs/modules/system/your-new-system.nix ];
+     };
+   };
+   ```
+4. ***IF YOU WANT TO CHECK IT MANUALLY*** - **Test the configuration** before deploying, change the `nixos-your-system` accordingly:
+   ```bash
+   nix build .#nixosConfigurations.nixos-your-system.config.system.build.toplevel
+   ```
+
+Once the build succeeds, the configuration is ready for deployment using the `pull.zsh` script on the target machine.
