Addons are modifications to the game that add either new parts or systems into the game that are not included with original install. They are made by the community and can greatly enhance your playing experience.

How to install addons

The simplest way is to copy over the folders to the appropriate directory in your KSP directory.

Most plugins come with multiple folders, usually housing the part and plugin files.


  • Tosh's Carts plugin zip file contains a folder called Carts134 (the last numbers are the version)
  • Inside of that folder are the folders "Parts", "Plugins", and "Source". There is also documentation called README_cart.txt
    • The "Parts" folder contains the actual ship-building parts you would see in the ship builder interface.
    • The "Plugins" folder contains the plugin .dll files that would support the plugin system implemented by Carts.
    • The "Source" folder is just the source code, and is only needed by modders wanting to see how Carts was made and maybe build from it (with permission/attribution, of course)
  • Since you only need what's in the "Parts" and "Plugins" folders, you can just unzip those folders to your main KSP directory. It will ask you if you want to overwrite/merge the folders and you would choose "Yes". They would then merge with your prexisting folders, putting the needed addon files in their right place.

All you have to do from there is start the game!

Uninstalling is just as simple as deleting the parts/plugins that were included with the mod. Note, any ships created with those plugins will not load next time you start your game.
