How to Use Steam Manifests & Lua Blueprints
Step-by-step guide to downloading, deploying, and routing Steam manifests on Windows 11, macOS Whisky, and Steam Deck.
Step 1: Search & Download Package
Search for your game on ManiLuaHub.com and download the verified ZIP package containing both the .lua script and key.vdf depot file.
Step 2: Place Files into Directories
Extract the archive: move the <appId>_public.lua file into the "plugins/lua/" folder and key.vdf into "data/".
Step 3: Launch Companion Client First
Start your desktop companion toolkit (e.g. SteamTools) and confirm that the local manifest routing engine status turns green.
Step 4: Launch Steam Client & Sync
Open your official Steam desktop client. Steam will automatically mount the game into your active library for downloading.
Facing Steam Error 101/105 or Throttled Depot Downloads?
Valve CDN edge nodes and Steam manifest servers can be throttled or blocked by regional ISP firewalls. We recommend GearUP Booster to establish low-latency dedicated gaming routes, eliminate packet loss, and unthrottle high-speed game downloads.
Multi-Platform Setup Pathways
Detailed installation pathways tailored for Windows, macOS Whisky, and Steam Deck.
Windows 10 / 11 Native Setup
On Windows operating systems, client tools function as a background hook process. Ensure your antivirus software (such as Windows Defender) whitelists the portable folder.
The default file path for placing Lua scripts is: C:\Program Files (x86)\SteamTools\plugins\lua\. Always ensure the file is named in the format <appId>_public.lua.
macOS (Apple Silicon M1/M2/M3/M4 & Intel)
Mac users can run Windows Steam inside a dedicated Whisky or CrossOver bottle. Create a Windows 10 64-bit bottle, install the Windows Steam client, and deploy scripts in the same container.
Virtual bottle file path: drive_c/Program Files (x86)/SteamTools/plugins/lua/.
Steam Deck (SteamOS 3.0+ Desktop Mode)
Hold down the Power button on your Steam Deck and select Switch to Desktop. Download the native Linux tarball edition and extract it to ~/.steamtools/.
Copy the downloaded manifest packages into ~/.steamtools/plugins/, run the sync script, and switch back to Gaming Mode to launch your games.
