We really recommend using the Fallout Mod Manager to install Project Nevada!
It will automatically copy the right files and take care of any conflicts with already installed mods.
So before you can get started, you have to choose whether you want to do the FOMM installation (recommended) or a manual installation.

Remember: The Core module is required in any case! If you don't like a specific feature, you can disable it in-game.

> Automated Installation with FOMM

1. Start FOMM and click on Package Manager.

2. In the top-right button menu, click on Add FOMod and select the downloaded archive file.

3. Project Nevada will now appear in the list. Select it and click Activate.

4. In the installer window, select the modules you want, then click Install. If you are prompted to overwrite anything, click Yes to All.

5. Done!
