This update does away with the clunky installation involving copying files in the assets folder. Instead, it is a single folder placed in the DLC folder of your Civ V installation, for easy enabling and disabling.
Because it's a beta, compatibility with other mods is uncertain, so if you have a compatibility issue, post it in the discussion topic, along with any solution if you've come up with one. I may not be able to help troubleshoot, but I will try, and hopefully others will be able to recommend any changes that make the mod more robust.
I'm relying on the community to help make this work, as I'm by no means an expert.
To install, unzip the archive and copy the RCI folder into the DLC folder of your Civ V installation (.../Sid Meier's Civilization V/Assets/DLC).
To uninstall, remove the folder from that same location.
