Mod selection is the first thing that pops up at worldgen, when you press “Create World”. The tab that says “Content” lists the mods. The left window is the list of mods currently available for adding to the world, the right window is the ones currently selected. Navigate between the two windows with the left and right arrow keys, and press enter to add/remove a mod, depending on what window you’re in. By default, Dark Days Ahead, Filthy Clothing, Disable NPC Needs, and Simplified Nutrition are selected, and can be removed at your leisure. Dark Days Ahead is the base game though, and thus can’t actually be removed, unless you want to render the world unplayable. Some mods are dependent on others, and selecting a dependent mod, without the one it’s dependent on will automatically add both to the mod selection window.
Pressing Tab will cycle between the three mod categories, Content, Blacklisting & Whitelisting, and Rebalance.
If you meant adding new mods to the selection screen though, the process is different. You probably also have to close the game before adding the new mods, so that the list can refresh once they’re added.
Many of them are available in the CDDA Downloader and Updater, but I’ve never tried to install them using that program, so I’m not sure quite how to do it. It was designed for ease-of-use though, so it can’t be terribly difficult.
To manually add mods, you’ll first need to download one, like this one (the OneDrive link is apparently the most current). It should download as a ZIP archive; most mods will.
Go to the directory where your copy of the game (the .exe) is located and find the folder, in that same directory, labeled “data”. Inside that will be a folder labeled “mods”. Inside that is where you’ll need to place the folder that is inside the
ZIP archive. Remember to get the folder inside the archive though, and not the archive itself.
After you have the folder in there, reboot the game, and they should show up on the mods list at worldgen, though they may not necessarily be under Content; they could be Blacklist/Whitelist, or Rebalancing mods.
Edit: When you have a satisfactory selection of mods at the mod selection screen, you can press “s” to save the list as default, and it will automatically produce that same list every time you make a new world with that version of the game. When you download a new version of the game though, it will probably reset again.
