+Minetest Δ (“Minetest Delta”) is a fork of Minetest-c55 <http://celeron.55.lt/~celeron55/minetest/>, incorporating experimental features that are not (yet) included in Minetest-c55.
+
+New features:
+* Submenu for key assignment (changes apply after restart)
+* configurable far mesh tree display (boolean)
+* configurable far mesh rendering distance
+* volumetric clouds (using fake shading)
+* translation support (including questionable translation into german)
+* build system uses local jthread & sqlite libraries if available
+
+New bricks:
+* Sandstone (crafted from 4 sand, yields sand)
+* Cactus (plant that grows on sand)
+* Clay (found in sand at sea level, yields 4 lumps of clay)
+* Brick (made from 4 clay bricks, yields 4 clay bricks)
+* Papyrus (plant that grows in shallow water)
+* Book shelf (made from 6 wood and 3 books, sandwhiched)
+* Rail (made from 6 iron ingots and 3 sticks, vertically sandwhiched)
+
+New materials:
+* Lump of clay
+* Clay brick (made from lumps of clay in the furnace)
+* Paper (made from 3 papyrus horizontally)
+* Book (made from 3 paper vertically)
+
+Alternate graphics:
+* Player
+* Omsk birds (instead of Oerkki ghosts)
+* Rat
+* Glass
+* Heart
+
+Building on GNU/Linux or OS X:
+    cmake . -DRUN_IN_PLACE=1
+    make -j2
+
+The “upstream” branch contains vanilla minetest-c55, created using:
+    hg-fast-export -r ~/share/src/games/minetest -o upstream
+    git push origin upstream/master:upstream -f
+
+All new/replaced graphics done by erlehmann are dual-licensed under GPL (version 2 or, at your option, any later version) and CC-BY-SA (version 3.0 or, at your option, any later version).

+Minetest-c55
+---------------
+An InfiniMiner/Minecraft inspired game.
+Copyright (c) 2010-2011 Perttu Ahola <celeron55@gmail.com>
+
+Further documentation:
+----------------------
+- Website: http://celeron.55.lt/~celeron55/minetest/
+- Wiki: http://celeron.55.lt/~celeron55/minetest/wiki/
+- Forum: http://celeron.55.lt/~celeron55/minetest/forum/
+
+This is a development version:
+------------------------------
+- Don't expect it to work as well as a finished game will.
+- Please report any bugs to me. That way I can fix them to the next release.
+	- debug.txt is useful when the game crashes.
+
+Controls:
+---------
+- See the in-game pause menu
+- Settable in the configuration file, see the section below.
+
+Map directory:
+--------------
+- Map is stored in a directory, which can be removed to generate a new map.
+- There is a command-line option for it: --map-dir
+- For a RUN_IN_PLACE build, it is located in:
+		../map
+- Otherwise something like this:
+	Windows: C:\Documents and Settings\user\Application Data\minetest\map
+	Linux: ~/.minetest/map
+	OS X: ~/Library/Application Support/minetest/map
+
+Configuration file:
+-------------------
+- An optional configuration file can be used. See minetest.conf.example.
+- Path to file can be passed as a parameter to the executable:
+	--config <path-to-file>
+- Defaults:
+	- If built with -DRUN_IN_PLACE=1:
+		../minetest.conf
+		../../minetest.conf
+	- Otherwise something like this:
+		Windows: C:\Documents and Settings\user\Application Data\minetest\minetest.conf
+		Linux: ~/.minetest/minetest.conf
+		OS X: ~/Library/Application Support/minetest.conf
+
+Command-line options:
+---------------------
+- Use --help
+
+Compiling on GNU/Linux:
+-----------------------
+
+Install dependencies. Here's an example for Debian/Ubuntu:
+$ apt-get install build-essential libirrlicht-dev cmake libbz2-dev libpng12-dev libjpeg8-dev libxxf86vm-dev libgl1-mesa-dev
+
+Download source, extract (this is the URL to the latest of source repository, which might not work at all times):
+$ wget https://bitbucket.org/celeron55/minetest/get/tip.tar.gz
+$ tar xf tip.tar.gz
+$ cd minetest
+
+Build a version that runs directly from the source directory:
+$ cmake . -DRUN_IN_PLACE=1
+$ make -j2
+
+Run it:
+$ cd bin
+$ ./minetest
+
+- Use cmake . -LH to see all CMake options and their current state
+- If you want to install it system-wide (or are making a distribution package), you will want to use -DRUN_IN_PLACE=0
+- You can build a bare server or a bare client by specifying -DBUILD_CLIENT=0 or -DBUILD_SERVER=0
+- You can select between Release and Debug build by -DCMAKE_BUILD_TYPE=<Debug or Release>
+  - Note that the Debug build is considerably slower
+
+Compiling on Windows:
+---------------------
+
+- You need:
+	* CMake:
+		http://www.cmake.org/cmake/resources/software.html
+	* MinGW or Visual Studio
+		http://www.mingw.org/
+		http://msdn.microsoft.com/en-us/vstudio/default
+	* Irrlicht SDK 1.7:
+		http://irrlicht.sourceforge.net/downloads.html
+	* Zlib headers (zlib125.zip)
+		http://www.winimage.com/zLibDll/index.html
+	* Zlib library (zlibwapi.lib and zlibwapi.dll from zlib125dll.zip):
+		http://www.winimage.com/zLibDll/index.html
+	* And, of course, Minetest-c55:
+		http://celeron.55.lt/~celeron55/minetest/download
+- Steps:
+	- Select a directory called DIR hereafter in which you will operate.
+	- Make sure you have CMake and a compiler installed.
+	- Download all the other stuff to DIR and extract them into there. All those
+	  packages contain a nice base directory in them, which should end up being
+	  the direct subdirectories of DIR.
+	- You will end up with a directory structure like this (+=dir, -=file):
+	-----------------
+	+ DIR
+		- zlib-1.2.5.tar.gz

+	-----------------
+	- Start up the CMake GUI
+	- Select "Browse Source..." and select DIR/minetest
+	- Now, if using MSVC:
+		- Select "Browse Build..." and select DIR/minetest-build
+	- Else if using MinGW:
+		- Select "Browse Build..." and select DIR/minetest
+	- Select "Configure"
+	- Select your compiler
+	- It will warn about missing stuff, ignore that at this point. (later don't)
+	- Make sure the configuration is as follows
+	  (note that the versions may differ for you):
+	-----------------
+	BUILD_CLIENT             [X]
+	BUILD_SERVER             [ ]
+	CMAKE_BUILD_TYPE         Release
+	CMAKE_INSTALL_PREFIX     DIR/minetest-install
+	IRRLICHT_SOURCE_DIR      DIR/irrlicht-1.7.1
+	RUN_IN_PLACE             [X]
+	WARN_ALL                 [ ]
+	ZLIB_DLL                 DIR/zlib125dll/dll32/zlibwapi.dll
+	ZLIB_INCLUDE_DIR         DIR/zlib-1.2.5
+	ZLIB_LIBRARIES           DIR/zlib125dll/dll32/zlibwapi.lib
+	-----------------
+	- Hit "Configure"
+	- Hit "Generate"
+	If using MSVC:
+		- Open the generated minetest.sln
+		- The project defaults to the "Debug" configuration. Make very sure to
+		  select "Release", unless you want to debug some stuff (it's slower)
+		- Build the ALL_BUILD project
+		- Build the INSTALL project
+		- You should now have a working game with the executable in
+			DIR/minetest-install/bin/minetest.exe
+		- Additionally you may create a zip package by building the PACKAGE
+		  project.
+	If using MinGW:
+		- Using the command line, browse to the build directory and run 'make'
+		  (or mingw32-make or whatever it happens to be)
+		- You should now have a working game with the executable in
+			DIR/minetest/bin/minetest.exe
