 Написанный с нуля сервер **Minecraft 1.12.2**.
 
-На данный момент может только показывать информацию о себе. Подключение к серверу не возможно.
+На данный момент сервер может показывать о себе информацию в списке серверов (motd, онлайн, иконка) и позволять
+игрокам подключиться к себе. Загружается пустой мир.
