Installing mods
Installation
Finding and installing mods which is short for modification to RimWorld is a very easy task to do if you want to add some new content to your game. First, you need to look online and find a mod that you want to try out. Remember, the main source for finding mods is the forum in the mod release section. Once you find a mod you like that is compatible with the version of RimWorld you have, or even a few mods you like you can download them from their individual threads.
Windows
Once you have downloaded a mod and opened up your zip files you just got, it's just a simple case of drag and dropping the extracted zip files into your RimWorld mods folder, starting up your game, and activating the mods. However, be aware that many mods require you to start a new game before the new content is available.
Mac
To install the mods you have downloaded, go to your applications folder where you can find the RimWorld application. Right click on the RimWorld app and select 'show package contents'. This is where the mods folder is located and to install mods just extract the downloaded mod into a folder inside the mods folder.
Editing mods folder
When editing your mods folder, you should always make a backup somewhere (such as your desktop) in case you come across errors. This way, you will always be able to undo a mistake that may occur. It is also very important to never delete the ThingCategories.xml file in your mod pack; doing this will result in a black screen when trying to start the game up.
Compatibility
Not all mods work with each other. You will know if you have incompatible mods if you are having serious gameplay issues, such as unplaceable items, graphical issues, colonists getting stuck, etc.
