This guide: https://www.nexusmods.com/cyberpunk2077/mods/1820 is (I think) the best place to start. It can be found on below Discord server as well, but easier for you with direct link. Afterwards, CP77 Modding Community Discord server is very good place for learning more advanced things and ask for support: https://discord.com/invite/cp77modding I am also completely noob for games modding (I mean, I am a hobbyist familiar with Blender, VFX and 3D, but never before touched some game modding), but following guide above and reading Discord, I published my first (very simple) mod yesterday: https://www.nexusmods.com/cyberpunk2077/mods/1842 and was able to replace tone of in-game billboards with my private family photos (of course, this second wasn't published :) ). Nothing special, but without guide above I wouldn't know where to start same as you.
