+# Contributing
+
+Contributions are welcome! Here's how you can help:
+
+- [Contributing code](#code)
+- [Reporting issues](#issues)
+- [Requesting features](#feature-requests)
+- [Translating](#translations)
+- [Donating](#donations)
+
+## Code
+
+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.
+
+3. Start coding!
+    - Refer to the [Lua API](https://github.com/minetest/minetest/blob/master/doc/lua_api.txt), [Developer Wiki](http://dev.minetest.net/Main_Page) and other [documentation](https://github.com/minetest/minetest/tree/master/doc).
+    - Follow the [C/C++](http://dev.minetest.net/Code_style_guidelines) and [Lua](http://dev.minetest.net/Lua_code_style_guidelines) code style guidelines.
+    - Check your code works as expected and document any changes to the Lua API.
+
+4. Commit & [push](https://help.github.com/articles/pushing-to-a-remote/) your changes to a new branch (not `master`, one change per branch)
+    - Commit messages should:
+        - Use the present tense.
+        - 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.
+    - The second line should be empty.
+    - The following lines should describe the commit, starting a new line for each point.
+
+5. Once you are happy with your changes, submit a pull request.
+     - Open the [pull-request form](https://github.com/minetest/minetest/pull/new/master).
+     - Add a description explaining what you've done (or if it's a work-in-progress - what you need to do).
+
+### A pull-request is considered merge-able when:
+
+1. It follows the roadmap in some way and fits the whole picture of the project: [roadmap introduction](http://c55.me/blog/?p=1491), [roadmap continued](https://forum.minetest.net/viewtopic.php?t=9177)
+2. It works.
+3. It follows the code style for [C/C++](http://dev.minetest.net/Code_style_guidelines) or [Lua](http://dev.minetest.net/Lua_code_style_guidelines).
+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.
+
+## Issues
+
+If you experience an issue, we would like to know the details - especially when a stable release is on the way.
+
+1. Do a quick search on GitHub to check if the issue has already been reported.
+2. Is it an issue with the Minetest *engine*? If not, report it [elsewhere](http://www.minetest.net/development/#reporting-issues).
+3. [Open an issue](https://github.com/minetest/minetest/issues/new) and describe the issue you are having - you could include:
+     - Error logs (check the bottom of the `debug.txt` file).
+     - Screenshots.
+     - Ways you have tried to solve the issue, and whether they worked or not.
+     - Your Minetest version and the content (games, mods or texture packs) you have installed.
+     - Your platform (e.g. Windows 10 or Ubuntu 15.04 x64).
+
+After reporting you should aim to answer questions or clarifications as this helps pinpoint the cause of the issue (if you don't do this your issue may be closed after 1 month).
+
+## Feature requests
+
+Feature requests are welcome but take a moment to see if your idea follows the roadmap in some way and fits the whole picture of the project: [roadmap introduction](http://c55.me/blog/?p=1491), [roadmap continued](https://forum.minetest.net/viewtopic.php?t=9177). You should provide a clear explanation with as much detail as possible.
+
+## Translations
+
+Translations of Minetest are performed using Weblate. You can access the project page  with a list of current languages [here](https://hosted.weblate.org/projects/minetest/minetest/).
+
+## Donations
+
+If you'd like to monetarily support Minetest development, you can find donation methods on [our website](http://www.minetest.net/development/#donate).
+
+# Maintaining
+
+*This is a concise version of the [Rules & Guidelines](http://dev.minetest.net/Category:Rules_and_Guidelines) on the developer wiki.*
+
+These notes are for those who have push access Minetest (core developers / maintainers).
+
+- See the [project organisation](http://dev.minetest.net/Organisation) for the people involved.
+
+## Reviewing pull requests
+
+Pull requests should be reviewed and, if appropriate, checked if they achieve their intended purpose. You can show that you are in the process of, or will review the pull request by commenting *"Looks good"* or something similar.
+
+**If the pull-request is not [merge-able](#a-pull-request-is-considered-merge-able-when):**
+
+Submit a comment explaining to the author what they need to change to make the pull-request merge-able.
+
+- If the author comments or makes changes to the pull-request, it can be reviewed again.
+- If no response is made from the author within 1 month (when improvements are suggested or a question is asked), it can be closed.
+
+**If the pull-request is [merge-able](#a-pull-request-is-considered-merge-able-when):**
+
+Submit a :+1: (+1) or "Looks good" comment to show you believe the pull-request should be merged. "Looks good" comments often signify that the patch might require (more) testing.
+
+- Two core developers must agree to the merge before it is carried out and both should +1 the pull request.
+- Who intends to merge the pull-request should follow the commit rules:
+    - The title should follow the commit guidelines (title starts with a capital letter, present tense, descriptive).
+    - Don't modify history older than 10 minutes.
+    - Use rebase, not merge to get linear history:
+    - `curl https://github.com/minetest/minetest/pull/1.patch | git am`
+
+## Reviewing issues and feature requests
+
+- If an issue does not get a response from its author within 1 month (when requiring more details), it can be closed.
+- When an issue is a duplicate, refer to the first ones and close the later ones.
+- Tag issues with the appropriate [labels](https://github.com/minetest/minetest/labels) for devices, platforms etc.

+# Security Policy
+
+## Supported Versions
+
+We only support the latest stable version for security issues.
+See the [releases page](https://github.com/minetest/minetest/releases).
+
+## Reporting a Vulnerability
+
+We ask that you report vulnerabilities privately, by contacting a core developer,
+to give us time to fix them. You can do that by emailing one of the following addresses:
+
+* celeron55@gmail.com
+* rubenwardy@minetest.net
+
+Depending on severity, we will either create a private issue for the vulnerability
+and release a patch version of Minetest, or give you permission to file the issue publicly.
+
+For more information on the justification of this policy, see
+[Responsible Disclosure](https://en.wikipedia.org/wiki/Responsible_disclosure).

+- 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`

+
+#### 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 "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
+
+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`.

+
+### 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 --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.
+
+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=0 -DENABLE_CURSES=0
+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`.

-$ tar xf minetest_game.tar.gz
-$ mv minetest-minetest_game-* minetest_game
-$ cd ..
-
-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>
-  - 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
-	* 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.php
-- 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
-	- 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-1.7.1.zip
-		- 110214175330.zip (or whatever, this is the minetest source)
-		+ zlib-1.2.5
-			- zlib.h
-			+ win32
-			...
-		+ zlib125dll
-			- readme.txt
-			+ dll32
-			...
-		+ irrlicht-1.7.1
-			+ lib
-			+ include
-			...
-		+ 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-1.7.1
-	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
-	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
-	-----------------
-	- 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
-
