 IrrlichtMt version 1.9
 ======================
 
-IrrlichtMt is the 3D engine of [Minetest](https://github.com/minetest).
+The Irrlicht Engine is an open source realtime 3D engine written in C++.
-It is based on the [Irrlicht Engine](https://irrlicht.sourceforge.io/) but is now developed independently.
+
+This is a fork by the [Minetest](https://github.com/minetest) developers that was stripped-down and customized specifically for use in Minetest.
 It is intentionally not compatible to upstream and is planned to be eventually absorbed into Minetest.

+The Win32-VisualStudio version is currently (Irrlicht 1.8) compiled with VS 2010 using the Windows 7.1 SDK as platform toolset.
+You might get the necessary Windows Platform SDK here: http://msdn.microsoft.com/en-us/windows/bb980924.aspx
+
+To link to that Irrlicht.dll you need to set platform toolset in your VS version to the same target or re-compile the Irrlicht.dll using another platform toolset.
+
+To re-compile Irrlicht for Win32-VisualStudio:
+There are several project files for different VS versions in source/Irrlicht.
+Irrlicht10.0.sln is for VS 2010
+Irrlicht11.0.sln is for VS 2012
+Irrlicht12.0.sln is for VS 2013
+
+To compile Irrlicht + all examples and all tools check the BuildAllExamples_*.sln files in the examples folder.
+
+For newer VS versions you have update one of those projects (VS usually can do that automatically when you open an older solution file).
+
+Currently each of those solutions does set the platform toolset "Windows 7.1 SDK" (to be compatible to each other). 
+You might want to change that in the project settings and set it to your current version.
+Make sure you use the same platform toolset in your application and in the engine.
+Also when compiling examples each example has to use the same platform toolset as was used for the engine.
+
+Platform should be Win32
+Configuration is by default "Release"
+But you can also chose "Debug" if you want Irrlicht with Debug information.
+Static builds are possible but you have to additionally set the _IRR_STATIC_LIB_ define in the application when linking to a static Irrlicht.lib

+If you wish to compile Irrlicht for Win32-gcc you have several choices.

+1. You can work from within a MinGW shell.
+Go to the folder source/Irrlicht and run the Makefile with:

+Examples can be build by going into the folder of the example (for example examples/01.HelloWorld) and running the Makefile with:

+2. Use the Code::Blocks IDE
+There is a project file called Irrlicht-gcc.cbp in source/Irrlicht to compile just the engine.
+Be sure to select a Windows target like "Win32 - release - accurate math - dll"

+There is also Code::Blocks workspace file in the examples folder called BuildAllExamples.workspace

+Checklist for Irrlicht developers doing releases.
+
+Note: Generally the more platforms, compilers, settings you can test the better. Ask for help for platforms which you don't own.
+
+- PRE-BUILD TESTS:
+- - Run tests in the tests folder
+- - Compile and run examples.
+- - Compile and run the tools. Note that some tools are in the buildall-examples VS project files on Windows, 
+    but on Linux command line you have to compile them individually.
+
+- VERSION UPDATES:
+- - check IRRLICHT_SDK_VERSION (in IrrCompileConfig.h)
+- - check version number in the Makefile
+- - update readme.txt (version number, supported compilers)
+- - Add new release information (date+version-number) in changes.txt
+- - go through folders if other .txt files still make sense (things change and updating those files tends to be forgotten)
+
+- DOCUMENTATION UPDATES:
+- - run makedocumentation.sh in scripts\doc\irrlicht
+- - run maketutorial.sh in scripts\doc\irrlicht (commit changed tutorial.html's)
+
+- BUILDING THE RELEASE
+  (TBD - should we still release dll's? Newer and older VS builds are no longer compatible anyway)
+- - run a clean build for buildAllExamples in the examples folder with the 
+    target compiler for 32-bit and for release (old VS compiler - so far VS2010)
+- - when possible compile the dll for MinGW on Windows (in release and with -s for smaller size)
+- - when possible compile the dll for 64 bit (again with Visual Studio and release)
+- - create a target directory, like irrlicht-1.8.1 for example
+- - svn export to the target directory
+- - copy the subfolders of doctemp into the doc folder of the target directory
+    careful, this should only be one(!) subfolder (we ended up with copies before, maybe Windows/Linux builds use different names?)
+- - copy all .exe files (except test.exe) from bin\Win32-VisualStudio (.pdb's are not necessary)
+- - copy Irrlicht.dll from bin\Win32-visualstudio 
+- - copy the files in lib\Win32-visualstudio
+- - copy Irrlicht.dll from bin\Win64-VisualStudio 
+- - copy the files in lib\Win64-visualstudio 
+- - copy Irrlicht.dll from bin\Win32-gcc 
+- - copy the files in lib\Win32-gcc
+- - remove the tests folder
+- - remove scripts folder (if the release comes with docs, if you do a release 
+without docs for smaller filesizes then the script folder has to stay in).
+- - create a zip file 
+- - figure out how to fix unix access right for shell-scripts in the zip file (my 
+trick so far is: unzip in Linux, set +x for all .sh files, zip again)
+
+RELEASING:
+- - upload the zip-file somewhere, then download it again on all platforms and do 
+  another quick test with that file (do examples still run, can you compile)
+- - give the link to the zip out on the mailinglist for others to look at
+- - Upload new documentation (the content of doc/html) to: web.sourceforge.net 
+  (sftp protocol, user and passwd are your sourceforge account, the folder 
+  might not be shown - but you can still cd into it!):
+  /home/project-web/i/ir/irrlicht/htdocs 
+  Best create first a folder with a new name, copy stuff in there, test (just 
+  check the website), rename old folder and give new folder the "docu" name. 
+  Then you can delete the old folder if you want.
+- - upload the zip by logging in to sourceforge and using the "Files" menu (needs 
+	admin privileges and it's the 'Files' menu between 'Summary' and 'Reviews'). 
+	The target is in one of the Irrlicht SDK subfolders. Then click the "i" beside 
+	the file and "select all" to make it the active download.
+- - write a forum post, tell everyone in facebook, reddit, your friends...
+- - login to wordpress at http://irrlicht.sourceforge.net/wp-login.php, update the 
+	downloads section and write a release post.

+The Irrlicht Engine SDK version 1.9
+==========================================================================
+
+  Welcome to the Irrlicht Engine SDK.
+
+  Content of this file:
+
+  1. Directory Structure Overview
+  2. How To Start
+  3. Requirements
+  4. Release Notes
+  5. License
+  6. Contact
+
+
+==========================================================================
+1. Directory Structure Overview
+==========================================================================
+
+  You will find some directories after uncompressing the archive of the
+  SDK. These are:
+
+  \bin         The compiled library Irrlicht.DLL and some compiled demo
+               and example applications, just start them to see the
+               Irrlicht Engine in action. Windows only.
+  \doc         Documentation of the Irrlicht Engine.
+  \examples    Examples and tutorials showing how to use the engine with
+               C++.
+  \include     Header files to include when programming with the engine.
+  \lib         Libs to link with your programs when using the engine.
+  \media       Graphics and sound resources for the demo applications and
+               examples.
+  \source      The source code of the Irrlicht Engine. This code is
+               not needed to develop applications with the engine,
+               but it is included to enable recompilation and
+               debugging, if necessary.
+  \tools       Useful tools (with sourcecode) for the engine.
+
+
+
+==========================================================================
+2. How to start
+==========================================================================
+
+  To see the engine in action in Windows, just go to the \bin\Win32-VisualStudio
+  directory, and start some applications. There should also be an
+  application named Demo.exe which should show the most
+  interesting features of Irrlicht.
+
+  To start developing own applications and games with the engine take
+  a look at the 01.HelloWorld example in the \examples directory.
+  There is also a .html file with a tutorial which should be
+  easily comprehensible.
+
+  The Irrlicht Engine is a static lib under linux. A precompiled version can be
+  generated from the sources using the Makefile in source/Irrlicht. Run 'make' in 
+  that subfolder. After this you should be able to 'make' all
+  example applications in /examples by calling the buildAllExamples script. You 
+  can run the examples then from the bin folder.
+
+  It is also possible to use Irrlicht as shared object
+  (libIrrlicht.so.versionNumber). Use the proper makefile target for this by
+  running 'make sharedlib' in the source folder. See the Makefile for details.
+
+  For OSX you can find an XCode project file in source/Irrlicht/MacOSX. This will
+  build the libIrrlicht.a library necessary to create the apps.
+
+==========================================================================
+3. Requirements
+==========================================================================
+
+  You can use one of the following compilers/IDEs to develop applications
+  with Irrlicht or recompile the engine. However, other compilers/IDEs may
+  work as well, we simply didn't test them.
+
+  * gcc 4.x
+  * Visual Studio 2010(10.0)-2013(12.0)
+  * Code::Blocks (& gcc or visual studio toolkit)
+  
+  If you ever want to (re)compile the engine yourself (which means you don't
+  want to use the precompiled version) you need the following:
+
+  * Windows:
+	* Needed: PlatformSDK (which usually comes with all IDEs, download
+			it separately for MSVC Express 2005)
+	* Optional: DirectX SDK, for D3D9 support
+	* Optional: DirectX SDK prior to May 2006, for D3D8 support
+
+  * Linux:
+	* Needed: XServer with include files
+	* Optional: OpenGL headers and libraries (libGL.so) for OpenGL support
+		GLX +
+		XF86VidMode [package x11proto-xf86vidmode-dev] or XRandr
+		(X11 support libraries, the latter two for fullscreen mode)
+
+  * OSX:
+	* Needed: XCode and Cocoa framework
+	* Needed: OpenGL headers and libraries
+
+==========================================================================
+4. Release Notes
+==========================================================================
+
+  Informations about changes in this new version of the engine can be
+  found in changes.txt.
+
+  Please note that the textures, 3D models and levels are copyright
+  by their authors and not covered by the Irrlicht engine license.
+
+==========================================================================
+5. License
+==========================================================================
+
+  The license of the Irrlicht Engine is based on the zlib/libpng license.
+  Even though this license does not require you to mention that you are
+  using the Irrlicht Engine in your product, an acknowledgement
+  would be highly appreciated.
+
+  Please note that the Irrlicht Engine is based in part on the work of
+  the Independent JPEG Group, the zlib, and libpng. This means that if you use
+  the Irrlicht Engine in your product, you must acknowledge somewhere
+  in your documentation that you've used the IJG code and libpng. It would
+  also be nice to mention that you use the Irrlicht Engine and the zlib.
+  See the README files in the jpeglib and the zlib for
+  further informations.

+This branch is used for development of the OpenGL-ES drivers for Irrlicht.
+There will be drivers for ogl-es 1.x and 2.x at some time, but we'll start
+with 1.x first. Both drivers will be separate drivers, loosely based on the
+OpenGL driver.
+The branch is based on SVN/trunk and will be updated only very slowly. It's
+not intended for regular use besides when working with ogl-es development.
