+
+This mod adds a bed to Minetest which allows to skip the night.
+To sleep, rightclick the bed. If playing in singleplayer mode the night gets skipped
+immediately. If playing multiplayer you get shown how many other players are in bed too,
+if all players are sleeping the night gets skipped. The night skip can be forced if more
+than 50% of the players are lying in bed and use this option.
+
+Another feature is a controlled respawning. If you have slept in bed (not just lying in
+it) your respawn point is set to the beds location and you will respawn there after
+death.
+You can disable the respawn at beds by setting "enable_bed_respawn = false" in
+minetest.conf.
+You can disable the night skip feature by setting "enable_bed_night_skip = false" in
+minetest.conf or by using the /set command in-game.

+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 (WTFPL).
+
+
+[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
