TS3 mods are package based content and require the Framework to be inserted into the player's TS3 user game folder in Documents in order to work. It's really just three folders nested correctly and the one require Resource.cfg file. The mods, or other forms of package based content, go into Mods\Packages once unzipped.
This version of the Framework is downloadable in its entirety and comes with two small sample script mods that can be used for testing and then kept or removed as desired.
