Start with an importable project

Inspect the folder first

Download Patrol Pair and extract a working copy, mod-info.txt names the project in the mod list, while units contains the configurations and images, keep mod-info.txt at the archive root

01-patrol-pair/
├─ mod-info.txt
└─ units/
   ├─ scout.ini
   ├─ guard.ini
   ├─ body.png
   ├─ guard.png
   └─ turret.png

Give the mod a recognizable title

Open mod-info.txt in a UTF-8 text editor, change title and keep the minimum version at 1.15, use description to say what the player receives, unit sections belong in their own files

[mod]
# 教程配套项目 / Tutorial project
title: Patrol Pair
description: Two ground vehicles for learning unit basics and inheritance
minVersion: 1.15

Import and find both vehicles

Import the original .rwmod through the game mod manager, enable it and reload, search for Patrol or the unit ID in the sandbox, confirm that both vehicles appear before changing code

Change one thing at a time

First change the scout display name, save, repackage and reload, once the new name appears, move on to health and speed, retain the downloaded original as a rollback copy
