xixas: This is just a quick HOWTO for anyone trying to get the official CP2077 REDmod mod manager up and running without using the Galaxy client -- as documentation for doing so doesn't seem to be posted anywhere.

I'm playing on a Linux machine at the moment, so I'll mention the Wine-related bits as well.

Tested environment:
• Cyberpunk 2077: 1.61_(64bit)_(60064) (link)
• Cyberpunk 2077 REDmod: 1.61_(64bit)_(60064) (link)
• Manjaro Linux (up to date, 2022-01-22)
• Lutris
• Wine Runner: lutris-7.2.2-x86_64
• Winetricks 20220411-1

Assuming you already have a working CP2077 installation from the offline installer --
If using Lutris, the included winetricks is often broken. Ensure you have winetricks installed and "Use system winetricks" is ENABLED under Configure>Runner Options.

REDmod Launcher Requirements:
• Use winetricks to install vcrun2019
• In the Wine Configuration, ensure Windows Version is set to Windows 10
• Install REDmod - if using Lutris, do this via "Run EXE inside Wine prefix" from the wine glass menu at the bottom of the window

From now on, load the game using "GOG Games/Cyberpunk 2077/REDprelauncher.exe" (instead of the usual "Launch Cyberpunk 2077.lnk" or "Cyberpunk2077.exe").

In the Pre-launcher's settings (see attached screenshot), ensure "Enable mods" is enabled and then click Play.

For details on installing mods via REDmod, see "HOW CAN I INSTALL MODS FOR CYBERPUNK 2077?" at https://www.cyberpunk.net/en/modding-support.

You'll have to verify REDmod compatibility on a per-mod basis.

There are a number of REDmod-based mods over at NexusMods these days, so you might also want to take a look at the NexusMods REDmod Modding Tool - All You Need to Know
