## What it is
The Nexus Mod Manager (NMM) is a free, open-source Windows desktop application for downloading, installing, updating, and managing game mods through a graphical interface. It integrates with Nexus Mods sites to enable one-click downloads and installs for dozens of supported games like Skyrim, Fallout 4, Cyberpunk 2077, and Baldur's Gate 3.

## Use cases
- download and install mods for Skyrim with one click
- manage and toggle which mods are active for Fallout 4
- pause and resume large mod downloads
- keep Cyberpunk 2077 mods updated from Nexus Mods
- cleanly uninstall mods without leftover files
- try different mod configurations and profiles quickly

## When to choose
- you mod games supported by NMM and want a simple Windows GUI integrated with Nexus Mods
- you need one-click downloads from Nexus Mods sites into a manager
- you want a free, ad-free, open-source mod manager

## When to avoid
- you use Linux or macOS - NMM is Windows-only on .NET Framework
- you want a modern actively developed manager - consider Vortex or Mod Organizer 2 instead
- your game is not on the supported games list
