This is a community designed tech tree designed to support as many mods as possible and extend the KSP tech tree without affecting the stock tree.
Forum thread: http://forum.kerbalspaceprogram.com/threads/98409
To install, place the GameData folder inside your Kerbal Space Program folder. If asked to overwrite files, do so.
This mod is only a tech tree! It requires TechManager (http://forum.kerbalspaceprogram.com/threads/98293) version 1.4 or higher to function.
It also requires mods to support it for their parts to be added. Modders, see the included ForModders.txt file for how to support the Community Tech Tree
