Go to ''https://www.nexusmods.com/'' and create a free account.
Click on the option mods at the top of the website and then download the Vortex mod manager on the right top.
Once the download is done, install vortex onto your PC and open the program.
In vortex go to the tab games on the left side and search for the game ''Fallout 4'' and click on manage, Vortex will then ask you to tell it where the game is installed on your system and might want you to restart the program.
When that is done, reopen Vortex and minimize it.
Now Vortex is ready to use.

For MO2 go to ''https://www.nexusmods.com/skyrimspecialedition/mods/6194'' and click on files, then download the latest version by clicking on manual download.
When it's downloading you have to run the exe. to install the program, I would recommend to make a folder for it on your desktop and install it directly in there.
When you start the program up for the first time, it will ask you what game you want to manage and where it is located.
Now MO2 is ready to be used.

Now go back to the Nexus website and use the search bar to find the game Fallout 4.
Then scroll down to mods and click ''view all'', as of writing this guide there are 65,902 mods for Fallout 4 on the website.
Find yourself a mod you like and click on it, it will open the mod page and show you a description, some pictures.

When you find a mod you like, click on files, click on mod manager download and then slow download.
It will give you popup asking if you allow it to download it to vortex, it will also give you the option to auto allow it.
When you download it, it will maximize Vortex and start downloading the file in it.
When done go to the tab mods and click on the blue button to install the file.
Then enable the mod and now you are ready to play with the mod installed.
You can start the game like normal in steam or click left top in vortex on the game banner on the play button.

For MO2 you will have to manual download the file and drag it to the square on the left side of the MO2 program, just under profile.
Then left click on the file you just downloaded and click install.

Three IMPORTANT Notes:
1. make sure to see if a mod needs a requirement, on the description page it will tell you if and what is needed for the mod to work, it will then also give you the links to the mods.
2. make sure you check the amount of plugins you are using, you can see it in Vortex under the tab plugins and then look in the top right where it says active
for MO2 it shows on the right side next to active.
Your max is 255 plugins, not every mod will add plugins (Usually texture mods don't, but mods that add content do)
3. The next-gen update broke most mods on Nexus, it's recommended to downgrade your game.
Make sure to check which version a mod is meant for and which version you use on your game.
you can use this guide to downgrade the game easily: https://sp.zhabite.com/sharedfiles/filedetails/?id=3492270027
