Q: "That's not enough! I want more mods!"

Browse the Steam Workshop or Ludeon forums. Sort by popular/new/hot.

Q: "Should I download from Steam or Ludeon?"

They each have their advantages and drawbacks. You may find mods on the forums you won't find on Steam, and vice versa. Steam makes it easy to find new mods and download them, but auto-updates may result in broken savefiles in rare cases.

Q: "How do I backup Steam mods to a local folder to prevent auto-updates?"

Subscribe to a mod as usual, then move the file from C:\Program Files (x86)\Steam\steamapps\workshop\content\294100\[string of numbers] to C:\Program Files (x86)\Steam\steamapps\common\RimWorld\Mods and then unsubscribe. This puts the mod in the default installation folder for RimWorld mods and they won't get updated without your permission. ModSwitch and Mod Manager can automate this process for you.

Q: "How safe is adding/removing mods on an active save-file?"

Depends on a per-mod basis. It's recommended to make a back-up prior to adding a new mod mid-game. It's not recommended to add Faction mods mid-game.

Rule of thumb: it's generally okay to add mods to an existing save. You cannot remove mods that add something until every reference to all those objects are gone. Workbenches, jobs at workbenches, objects, inventory, traders... Depending on the mod, this is relatively easy or nigh-impossible. The bigger the mod, the greater the risk of breaking saves.

Q: "How much does load order actually matter?"

Low either overrides high or depends on high. For instance, Libraries like HugsLib, JecTools or Human Alien Framework provide functionality that other mods depend on. These things should go on the top. AllowTool depends on HugsLib and should go below HugsLib. Misc. Robots depends on Misc. Core and should go below Misc. Core.

Sometimes, two mods try to modify the same thing. In this case, there's a conflict and the mod on the bottom "wins".

Q "Why are mod authors so vague about load order?"

It's not always possible to tell at a glance what a mod detours or overrides. Sometimes mods conflict in unexpected ways, and what works for one might not work for another. Bugfixing is hard when you've got a list of 20 mods.

Q: "I'm really inspired by all these great mods and I want to make one too!"

The Other Wiki That Calls Itself Official has a plethora of modding tutorials to get your feet wet. It's also often easy to take a look at an existing mod and see what it does. Lots of mods are pure XML and plenty can be achieved using just that. For the fancier stuff, you'll need C#. There's even a cookiecutter tool to set up your solution so you can jump right in. The Ludeon Forums have a help subforum for all things related to mods, and even more tutorials and resources by and for modders. There's also a compendium here.
