 ## Code
 
+If you are planning to start some significant coding, you would benefit from asking first on [our IRC channel](http://www.minetest.net/irc/) before starting.
+
 1. [Fork](https://help.github.com/articles/fork-a-repo/) the repository and [clone](https://help.github.com/articles/cloning-a-repository/) your fork.
 
-2. Before you start coding, consider opening an [issue at Github](https://github.com/minetest/minetest/issues) to discuss the suitability and implementation of your intended contribution with the core developers. If you are planning to start some very significant coding, you would benefit from first discussing on our IRC development channel [#minetest-dev](http://www.minetest.net/irc/). Note that a proper IRC client is required to speak on this channel.

-        - Be descriptive. See the commit messages by core developers for examples.
-    - The first line should:
-        - Start with a capital letter.
-        - Be a compact summary of the commit.
-        - Preferably have less than 70 characters.
-        - Have no full stop at the end.

 4. The code's interfaces are well designed, regardless of other aspects that might need more work in the future.
 5. It uses protocols and formats which include the required compatibility.
 
-### Important note about automated GitHub checks
-
-When you submit a pull request, GitHub automatically runs checks on the Minetest Engine combined with your changes. One of these checks is called 'cpp lint / clang format', which checks code formatting. Because formatting for readability requires human judgement this check often fails and often makes unsuitable formatting requests which make code readability worse.
-
-If this check fails, look at the details to check for any clear mistakes and correct those. However, you should not apply everything ClangFormat requests. Ignore requests that make code readability worse and any other clearly unsuitable requests. Discuss in the pull request with a core developer about how to progress.

-* `user`  - User-created modifiable data
-
-Where each location is on each platform:
-
-* Windows .zip / RUN_IN_PLACE source:
-    * `bin`   = `bin`
-    * `share` = `.`
-    * `user`  = `.`
-* Windows installed:
-    * `bin`   = `C:\Program Files\Minetest\bin (Depends on the install location)`
-    * `share` = `C:\Program Files\Minetest (Depends on the install location)`
-    * `user`  = `%APPDATA%\Minetest`
-* Linux installed:
-    * `bin`   = `/usr/bin`
-    * `share` = `/usr/share/minetest`

-    * `user`  = `Contents/User OR ~/Library/Application Support/minetest`
-
-Worlds can be found as separate folders in: `user/worlds/`
-
-Configuration file
-------------------
-- Default location:
-    `user/minetest.conf`
-- This file is created by closing Minetest for the first time.
-- A specific file can be specified on the command line:
-    `--config <path-to-file>`
-- A run-in-place build will look for the configuration file in
-    `location_of_exe/../minetest.conf` and also `location_of_exe/../../minetest.conf`
-
-Command-line options
---------------------
-- Use `--help`

-
-#### Download
-
-You can install Git for easily keeping your copy up to date.
-If you don’t want Git, read below on how to get the source without Git.
-This is an example for installing Git on Debian/Ubuntu:
-
-    sudo apt install git
-
-For Fedora users:
-
-    sudo dnf install git
-
-Download source (this is the URL to the latest of source repository, which might not work at all times) using Git:
-
-    git clone --depth 1 https://github.com/minetest/minetest.git
-    cd minetest
-
-Download minetest_game (otherwise only the "Development Test" game is available) using Git:
-
-    git clone --depth 1 https://github.com/minetest/minetest_game.git games/minetest_game
-
-Download source, without using Git:
-
-    wget https://github.com/minetest/minetest/archive/master.tar.gz
-    tar xf master.tar.gz
-    cd minetest-master
-
-Download minetest_game, without using Git:
-
-    cd games/
-    wget https://github.com/minetest/minetest_game/archive/master.tar.gz
-    tar xf master.tar.gz
-    mv minetest_game-master minetest_game
-    cd ..
-
-#### Build
-
-Build a version that runs directly from the source directory:
-
-    cmake . -DRUN_IN_PLACE=TRUE
-    make -j$(nproc)
-
-Run it:
-
-    ./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=FALSE`.
-- You can build a bare server by specifying `-DBUILD_SERVER=TRUE`.
-- You can disable the client build by specifying `-DBUILD_CLIENT=FALSE`.
-- You can select between Release and Debug build by `-DCMAKE_BUILD_TYPE=<Debug or Release>`.
-  - Debug build is slower, but gives much more useful output in a debugger.
-- If you build a bare server you don't need to have Irrlicht installed.
-  - In that case use `-DIRRLICHT_SOURCE_DIR=/the/irrlicht/source`.
-
-### CMake options

-### Compiling on Windows
-
-### Requirements
-
-- [Visual Studio 2015 or newer](https://visualstudio.microsoft.com)
-- [CMake](https://cmake.org/download/)
-- [vcpkg](https://github.com/Microsoft/vcpkg)
-- [Git](https://git-scm.com/downloads)
-
-### Compiling and installing the dependencies
-
-It is highly recommended to use vcpkg as package manager.
-
-#### a) Using vcpkg to install dependencies
-
-After you successfully built vcpkg you can easily install the required libraries:
-```powershell
-vcpkg install irrlicht zlib curl[winssl] openal-soft libvorbis libogg sqlite3 freetype luajit gmp jsoncpp --triplet x64-windows
-```
-
-- `curl` is optional, but required to read the serverlist, `curl[winssl]` is required to use the content store.
-- `openal-soft`, `libvorbis` and `libogg` are optional, but required to use sound.
-- `freetype` is optional, it allows true-type font rendering.
-- `luajit` is optional, it replaces the integrated Lua interpreter with a faster just-in-time interpreter.
-- `gmp` and `jsoncpp` are optional, otherwise the bundled versions will be compiled
-
-There are other optional libraries, but they are not tested if they can build and link correctly.
-
-Use `--triplet` to specify the target triplet, e.g. `x64-windows` or `x86-windows`.
-
-#### b) Compile the dependencies on your own
-
-This is outdated and not recommended. Follow the instructions on https://dev.minetest.net/Build_Win32_Minetest_including_all_required_libraries#VS2012_Build
-
-### Compile Minetest
-
-#### a) Using the vcpkg toolchain and CMake GUI
-1. Start up the CMake GUI
-2. Select **Browse Source...** and select DIR/minetest
-3. Select **Browse Build...** and select DIR/minetest-build
-4. Select **Configure**
-5. Choose the right visual Studio version and target platform. It has to match the version of the installed dependencies
-6. Choose **Specify toolchain file for cross-compiling**
-7. Click **Next**
-8. Select the vcpkg toolchain file e.g. `D:/vcpkg/scripts/buildsystems/vcpkg.cmake`
-9. Click Finish
-10. Wait until cmake have generated the cash file
-11. If there are any errors, solve them and hit **Configure**
-12. Click **Generate**
-13. Click **Open Project**
-14. Compile Minetest inside Visual studio.
-
-#### b) Using the vcpkg toolchain and the commandline
-
-Run the following script in PowerShell:
-
-```powershell
-cmake . -G"Visual Studio 15 2017 Win64" -DCMAKE_TOOLCHAIN_FILE=D:/vcpkg/scripts/buildsystems/vcpkg.cmake -DCMAKE_BUILD_TYPE=Release -DENABLE_GETTEXT=OFF -DENABLE_CURSES=OFF -DENABLE_SYSTEM_JSONCPP=ON
-cmake --build . --config Release
-```
-Make sure that the right compiler is selected and the path to the vcpkg toolchain is correct.
-
-#### c) Using your own compiled libraries
-
-**This is outdated and not recommended**
-
-Follow the instructions on https://dev.minetest.net/Build_Win32_Minetest_including_all_required_libraries#VS2012_Build
-
-### Windows Installer using WiX Toolset
-
-Requirements:
-* [Visual Studio 2017](https://visualstudio.microsoft.com/)
-* [WiX Toolset](https://wixtoolset.org/)
-
-In the Visual Studio 2017 Installer select **Optional Features -> WiX Toolset**.
-
-Build the binaries as described above, but make sure you unselect `RUN_IN_PLACE`.
-
-Open the generated project file with Visual Studio. Right-click **Package** and choose **Generate**.
-It may take some minutes to generate the installer.
-
-
-Docker
-------
-We provide Minetest server Docker images using the GitLab mirror registry.
-
-Images are built on each commit and available using the following tag scheme:
-
-* `registry.gitlab.com/minetest/minetest/server:latest` (latest build)
-* `registry.gitlab.com/minetest/minetest/server:<branch/tag>` (current branch or current tag)
-* `registry.gitlab.com/minetest/minetest/server:<commit-id>` (current commit id)
-
-If you want to test it on a Docker server you can easily run:
-
-	sudo docker run registry.gitlab.com/minetest/minetest/server:<docker tag>
-
-If you want to use it in a production environment you should use volumes bound to the Docker host
-to persist data and modify the configuration:
-
-	sudo docker create -v /home/minetest/data/:/var/lib/minetest/ -v /home/minetest/conf/:/etc/minetest/ registry.gitlab.com/minetest/minetest/server:master
-
-Data will be written to `/home/minetest/data` on the host, and configuration will be read from `/home/minetest/conf/minetest.conf`.
-
-**Note:** If you don't understand the previous commands please read the official Docker documentation before use.
-
-You can also host your Minetest server inside a Kubernetes cluster. See our example implementation in [`misc/kubernetes.yml`](misc/kubernetes.yml).
-
-
-Version scheme
---------------
-We use `major.minor.patch` since 5.0.0-dev. Prior to that we used `0.major.minor`.
-
-- Major is incremented when the release contains breaking changes, all other
-numbers are set to 0.
-- Minor is incremented when the release contains new non-breaking features,
-patch is set to 0.
-- Patch is incremented when the release only contains bugfixes and very
-minor/trivial features considered necessary.
-
-Since 5.0.0-dev and 0.4.17-dev, the dev notation refers to the next release,
-i.e.: 5.0.0-dev is the development version leading to 5.0.0.
-Prior to that we used `previous_version-dev`.

+Compiling on GNU/Linux:
+-----------------------
+
+Install dependencies. Here's an example for Debian/Ubuntu:
+$ sudo apt-get install build-essential libirrlicht-dev cmake libbz2-dev libpng-dev libjpeg-dev libxxf86vm-dev libgl1-mesa-dev libsqlite3-dev libogg-dev libvorbis-dev libopenal-dev libcurl4-gnutls-dev libfreetype6-dev zlib1g-dev libgmp-dev libjsoncpp-dev
+
+For Fedora users:
+$ sudo dnf install make automake gcc gcc-c++ kernel-devel cmake libcurl* openal* libvorbis* libXxf86vm-devel libogg-devel freetype-devel mesa-libGL-devel zlib-devel jsoncpp-devel irrlicht-devel bzip2-libs gmp-devel sqlite-devel luajit-devel leveldb-devel ncurses-devel doxygen spatialindex-devel bzip2-devel
+
+You can install git for easily keeping your copy up to date.
+If you don’t want git, read below on how to get the source without git.
+This is an example for installing git on Debian/Ubuntu:
+$ sudo apt-get install git
+
+For Fedora users:
+$ sudo dnf install git
+
+Download source (this is the URL to the latest of source repository, which might not work at all times) using git:
+$ git clone --depth 1 https://github.com/minetest/minetest.git
+$ cd minetest
+
+Download minetest_game (otherwise only the "Minimal development test" game is available) using git:
+$ git clone --depth 1 https://github.com/minetest/minetest_game.git games/minetest_game
+
+Download source, without using git:
+$ wget https://github.com/minetest/minetest/archive/master.tar.gz
+$ tar xf master.tar.gz
+$ cd minetest-master
+
+Download minetest_game, without using git:
+$ cd games/
+$ wget https://github.com/minetest/minetest_game/archive/master.tar.gz
+$ tar xf master.tar.gz
+$ mv minetest_game-master minetest_game
+$ cd ..
+
+Build a version that runs directly from the source directory:
+$ cmake . -DRUN_IN_PLACE=TRUE
+$ make -j <number of processors>
+
+Run it:
+$ ./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=FALSE
+- You can build a bare server by specifying -DBUILD_SERVER=TRUE
+- You can disable the client build by specifying -DBUILD_CLIENT=FALSE
+- You can select between Release and Debug build by -DCMAKE_BUILD_TYPE=<Debug or Release>
+  - Debug build is slower, but gives much more useful output in a debugger
+- If you build a bare server, you don't need to have Irrlicht installed.
+  In that case use -DIRRLICHT_SOURCE_DIR=/the/irrlicht/source

+Compiling on Windows:
+---------------------
+- This section is outdated. In addition to what is described here:
+  - In addition to minetest, you need to download minetest_game.
+  - If you wish to have sound support, you need libogg, libvorbis and libopenal
+
+- 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
+	* SQLite3 headers and library
+		https://www.sqlite.org/download.html
+	* Optional: gettext library and tools:
+		http://gnuwin32.sourceforge.net/downlinks/gettext.php
+		- This is used for other UI languages. Feel free to leave it out.
+	* And, of course, Minetest:
+		http://minetest.net/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.
+	  ("extract here", not "extract to packagename/")
+	  NOTE: zlib125dll.zip needs to be extracted into zlib125dll
+	  NOTE: You need to extract sqlite3.h & sqlite3ext.h from sqlite3 source
+	      and sqlite3.dll & sqlite3.def from sqlite3 precompiled binaries
+	      into "sqlite3" directory, and generate sqlite3.lib using command
+	      "LIB /DEF:sqlite3.def /OUT:sqlite3.lib"
+	- 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
+		- zlib125dll.zip
+		- irrlicht-1.8.3.zip
+		- sqlite-amalgamation-3130000.zip (SQLite3 headers)
+		- sqlite-dll-win32-x86-3130000.zip (SQLite3 library for 32bit system)
+		- 110214175330.zip (or whatever, this is the minetest source)
+		+ zlib-1.2.5
+			- zlib.h
+			+ win32
+			...
+		+ zlib125dll
+			- readme.txt
+			+ dll32
+			...
+		+ irrlicht-1.8.3
+			+ lib
+			+ include
+			...
+		+ sqlite3
+			sqlite3.h
+			sqlite3ext.h
+			sqlite3.lib
+			sqlite3.dll
+		+ gettext (optional)
+			+bin
+			+include
+			+lib
+		+ minetest
+			+ src
+			+ doc
+			- CMakeLists.txt
+			...
+	-----------------
+	- 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-1.8.3
+	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
+	GETTEXT_BIN_DIR          DIR/gettext/bin
+	GETTEXT_INCLUDE_DIR      DIR/gettext/include
+	GETTEXT_LIBRARIES        DIR/gettext/lib/intl.lib
+	GETTEXT_MSGFMT           DIR/gettext/bin/msgfmt
+	-----------------
+	- If CMake complains it couldn't find SQLITE3, choose "Advanced" box on the
+	  right top corner, then specify the location of SQLITE3_INCLUDE_DIR and
+	  SQLITE3_LIBRARY manually.
+	- If you want to build 64-bit minetest, you will need to build 64-bit version
+	  of irrlicht engine manually, as only 32-bit pre-built library is provided.
+	- Hit "Configure"
+	- Hit "Configure" once again 8)
+	- If something is still coloured red, you have a problem.
+	- 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
+		  and might not even work at all)
+		- 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 may need to copy some of the downloaded DLLs into bin/, see what
+		  running the produced executable tells you it doesn't have.
+		- You should now have a working game with the executable in
+			DIR/minetest/bin/minetest.exe
+
+Windows releases of minetest are built using a bat script like this:
+--------------------------------------------------------------------
+
+set sourcedir=%CD%
+set installpath="C:\tmp\minetest_install"
+set irrlichtpath="C:\tmp\irrlicht-1.7.2"
