-A simple [Jumpdrive](https://en.wikipedia.org/wiki/Jump_drive) for minetest
-
-Take your buildings with you on your journey

-* Forum topic: [https://forum.minetest.net/viewtopic.php?f=9&t=20073](https://forum.minetest.net/viewtopic.php?f=9&t=20073)
-
-# Operation
-
-* Place a 'jumpdrive:engine' into the center of your creation.
-* Connect the engine to a technic HV network
-* Let the engine charge
-* Choose your target coordinates (should be air or ignore blocks)
-* Select your cube-radius
-* Click "show" and check the green (source) and red (target) destination markers if everything is in range
-* Click "jump"
-
-# Compatibility
-
-Optional dependencies:
-* Mesecon interaction (execute jump on signal)
-* Technic rechargeable (HV)
-* Travelnet box (gets rewired after jump)
-* Elevator (on_place gets called after jump)
-* Locator (gets removed and added after each jump)
-* Pipeworks teleport tubes (with a patch to pipeworks)
-* Beds (thx to @tuedel)
-* Ropes (thx to @tuedel)
-* Mission-wand as coordinate bookmark (thx to @SwissalpS)
-* Areas
-* Drawers
-
-# Fuel
-
-The engine can be connected to a technic HV network or fuelled with power items.
-Power items are one of the following
-* `default:mese_crystal_fragment`
-* `default:mese_crystal`
-* `default:mese`
-
-# Energy requirements
-
-The energy requirements formula looks like this: **10 x radius x distance**
-
-For example:
-* Distance: 100 blocks
-* Radius: 5 blocks
-* Required energy: 10 x 5 x 100 = 5000
-
-# Upgrades
-
-If the `technic` mod is installed the following items can be used in the upgrade slot:
-* `technic:red_energy_crystal` increases power storage
-* `technic:green_energy_crystal` increases power storage
-* `technic:blue_energy_crystal` increases power storage
-* `technic:control_logic_unit` increases power recharge rate
-
-# Protection
-
-The source and destination areas are checked for protection so you can't remove and jump into someone else's buildings.

-
-# Advanced operation
-
-## Coordinate bookmarking
-
-You can place empty books into the drive inventory and write the coordinates to it with the "Write to book" button
-The "Read from book" reads the coordinates from the next book in the inventory
-
-## Diglines
-
-* See: [Digilines](doc/digiline.md)
-
-# Settings
-
-Settings in minetest.conf:
-
-* **jumpdrive.max_radius** max radius of the jumpdrive (default: *15*)
-* **jumpdrive.max_area_radius** max radius of the area jumpdrive (default: *25*)
-* **jumpdrive.powerstorage** power storage of the drive (default: *1000000*)
-* **jumpdrive.power_requirement** power requirement for chargin (default: *2500*)
-
-# Lua api
-
-## Preflight check
-
-The preflight check can be overriden to execute additional checks:
-
-```lua
-jumpdrive.preflight_check = function(source, destination, radius, player)
-	-- check for height limit, only space travel allowed
-	if destination.y < 1000 then
-		return { success=false, message="Atmospheric travel not allowed!" }
-	end
-
-	-- everything ok
-	return { success=true }
-end
-```
-
-## Fuel calc
-
-The default fuel calc can be overwritten by a depending mod:
-
-```lua
--- calculates the power requirements for a jump
-jumpdrive.calculate_power = function(radius, distance, sourcePos, targetPos)
-	return 10 * distance * radius
-end
-```
