+Carts (formerly boost_cart)
+==========================
+
+Carts, based almost entirely on the mod boost_cart [1], which
+itself is based on (and fully compatible with) the carts mod [2].
+
+The model was originally designed by stujones11 [3] (CC-0).
+
+Cart textures are based on original work from PixelBOX by Gambit (permissive
+license).
+
+
+[1] https://github.com/SmallJoker/boost_cart/
+[2] https://github.com/PilzAdam/carts/
+[3] https://github.com/stujones11/railcart/
+
+
+Features
+----------
+- A fast cart for your railway or roller coaster (up to 7 m/s!)
+- Boost and brake rails
+- Rail junction switching with the 'right-left' walking keys
+- Handbrake with the 'back' key
