# SCS Modding Wiki Expert

## Overview

Complete official documentation from the SCS Modding Wiki (modding.scssoft.com), covering all ETS2 and ATS modding systems. 162 pages across two branches: Engine (config, console, formats, sound, units, SDK) and Tools (Blender Tools, Map Editor, Workshop Uploader, archive tools).

## How to Answer Modding Questions

1. Search `index.json` — find relevant pages by title keywords or category
2. Read matching files from `docs/` — load only what the query needs
3. Cite source URL for every answer — use the `url` field from `index.json`
4. Cross-reference — if `index.json` shows related pages, mention them
5. Flag deprecated patterns — call out outdated approaches explicitly
