+Change the Minecraft port in `modules/machine/krile/configuration.nix`:
+
+```nix
+services.homestead.port = 25566;
+```
+
+The default is TCP 25565. When `services.homestead.openFirewall = true`, the
+opened TCP port follows this setting. Update your router's port forwarding and
+connect with `krile:25566` (or your server's address). Voice chat remains on
+UDP 24454, matching the pack's `config/voicechat/voicechat-server.properties`.
+Rebuild krile to apply the change.

 Change memory in the host configuration:
 
 ```nix
 services.homestead.jvmOpts = "-Xms6G -Xmx12G -XX:+UseG1GC";
 ```
 
+Declare operators in the host configuration:

+```nix
+services.homestead.operators = {
+  "YourMinecraftName" = {
+    uuid = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx";
+    level = 4;
+    bypassesPlayerLimit = false;
+  };
+};
+```
+
+Replace the example name and UUID with the player's actual Minecraft account
+details. A UUID string also works as a shorthand:
+`services.homestead.operators."YourMinecraftName" = "your-player-uuid";`.
+It defaults to permission level 4 and does not bypass the player limit.
+
+After rebuilding krile, nix-minecraft generates
+`/srv/minecraft/homestead/ops.json` when the server starts. A nonempty operator
+list replaces the file on each start, so changes made with `/op` or `/deop` do
+not persist across restarts. The default `{ }` leaves `ops.json` unmanaged.

 Other server settings use the underlying nix-minecraft options:

     max-players = 10;
     white-list = true;
