Installer is hosted on an external site rather than as a GitHub release, and Windows Defender exclusions are required for the install folder.

In plain English

This repository presents itself as Anvil Organizer, a Windows mod manager for Fallout 4. The README pitches it as a Mod Organizer 2 style tool with a virtual file system, support for the F4SE script extender, handling for Bethesda's BA2 archives, and management of .esp.esm, and .esl plugins. It claims that the game folder is never touched directly, so removing a mod leaves nothing behind. There is no GitHub release on the page. The single download button links to an external site, shawonline.co.za, rather than to a binary or source file on this repository. That kind of off-site installer link in a project that otherwise looks like a normal GitHub repo is worth pausing on before running the file. The README also instructs the reader to add an exclusion in Windows Defender during installation. The described feature set covers a virtual file system that stores mods outside the Fallout 4 install, a profile system for keeping separate loadouts such as a survival run or a settlement-building run, drag-and-drop installation from .zip.rar, or .7z archives, and capture of Nexus Mods links that use the Mod Manager Download button. Plugin sorting goes through LOOT and its masterlist, and the conflict view is meant to show which files one mod overrides in another. The stated usage path is to run setup.exe into a short path such as C:\Anvil, let the program auto-detect a Steam, Epic, or GOG copy of Fallout 4 or set the path by hand, pick a folder where downloaded mod archives will live, drag in archives or click Nexus links, double-click each one to install it, tick it on, press Sort, then choose either Launch F4SE or Launch Fallout 4. BA2 extraction is meant to happen on its own. Stated requirements are 64-bit Windows 10 or 11, any PC copy of Fallout 4, and around 500 MB for the program plus extra space for mods. The README mentions that Steam achievements stay on when launching through F4SE, and that a one-click backup captures the active plugins.txt and INI files. No source code, build steps, or license information appear in the README.
