Installation Guide

Download the file that matches your Minecraft version and mod loader. Use the NeoForge
build for Minecraft 1.21.1, or the Forge build for Minecraft 1.20.1.

Once the correct loader is installed, place New: Sim-U-Kraft into your mods folder. You
also need the matching version of LDLib / LDLib2 for your Minecraft version.

Gameplay

Start by placing a City Core to create your city. From there, you can claim chunks, manage
city funds, and begin growing a population of citizen NPCs.

Buildings are selected through the Build Box. Choose a building, preview it in the world,
confirm the placement, and let hired builders gather materials and construct it.

Citizens can take on different jobs such as builder, planner, farmer, commercial worker,
industrial worker, and logistics worker. Over time, your city can grow from a small base
into a living production network with homes, farms, shops, factories, warehouses, and item
routes.

Extra Notes

New: Sim-U-Kraft is designed for both singleplayer and dedicated servers. City data and NPC
work are handled by the server, while the client displays HUDs, screens, previews, and
status updates.

The mod includes English and Simplified Chinese localization, configurable client and
server options, and optional city highlighting support for Xaero's World Map.
