-## FreeSpace
-FreeSpace: The Great War (Released 1998) and FreeSpace 2 (1999) are mission-based space combat simulators, like X-Wing/TIE Fighter and Wing Commander. Among the greatest games of the genre, they were also effectively the last.
-
-The FreeSpace series follows humanity and their Vasudan allies as they fight to withstand the xenocidal, enigmatic Shivans, a species of unknown origin, vast technological capability, and seemingly limitless malice.
-
-## FreeSpace Open
-Thanks to Volition's generosity, we've continued development of FreeSpace 2 as FreeSpace Open, building graphical enhancements to bring the original games up to modern standards, telling new stories set in the FreeSpace universe and original worlds, and creating spectacular total conversions that let players fly in the beloved universes of Babylon 5, Battlestar Galactica, Wing Commander, and Star Wars.

-## Hard-Light Productions
-HLP is a fan community built on love and open-source code. We're dedicated to bringing modders together and giving them a place to share their own hard work and draw inspiration from the work of others. Thanks to Volition's generosity, we've continued development of FreeSpace 2 as FreeSpace Open, building graphical enhancements to bring the original games up to modern standards, telling new stories set in the FreeSpace universe and original worlds, and creating spectacular total conversions that let players fly in the beloved universes of Babylon 5, Battlestar Galactica, Wing Commander, and Star Wars.

-## How to get the game
-FreeSpace Open requires a retail installation of FreeSpace 2, which is available at the following stores: 
- - [GOG.com](https://www.gog.com/game/freespace_2)
- - [Steam](https://store.steampowered.com/app/273620/Freespace_2/)  
-After installing retail FS2, use [Knossos](https://fsnebula.org/knossos/) to upgrade to the most recent release of FSO. Knossos is an advanced mod manager and launcher for FSO.
-
-## Improvements
-The new open source game engine has several distingushing features including:
- - Linux and Mac OS X support
- - OpenGL support
- - OpenAL audio support
- - Easy mod installation
- - OGG support
- - Hardware transform, clipping, and lighting
-
-## The FreeSpace Upgrade Project
-While the SCP improves the code of the game engine to enable new and exciting features, the FreeSpace Upgrade Project (FSU) creates material that takes advantage of the improved game engine.  
-The FSU improves the ships, effects, and background elements of FreeSpace 2. Every now and then these improvements are released as a pack called MediaVPs. These assorted improvements enhance the graphics of the game.  
-While the best way to experience the FSU is by playing the game with it, you can watch this [comparison video](https://www.youtube.com/watch?v=RM1YC_gK-qo) between 1999 and 2019 to have an idea of how much more beautiful FSU makes the game.

-# Changelog
-All notable changes to this project will be documented in this file.
-
-The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
-
-## [19.0.0] - 2020-01-25 ([Thread](https://www.hard-light.net/forums/index.php?topic=96226.0))
-### Meta
- With this release we decided to drop the "`3.Major_revision.Minor_revision`" versioning scheme in favor of a year based scheme since the Major and Minor versions did not have much meaning anymore. Instead the scheme will now be "`<year>.<number that is incremented every release>.0`". The last 0 is still there because some of our systems expect that. It will be gone at some point.
-### Added
- Full Unicode text support: You can now use non-ASCII characters without having to worry about special fonts and special characters. This is an opt-in mod flag.
- Translation features for making it easier to only distribute one version of a mod which includes all languages.
- OpenAL Soft is included by default in binary distributions of FSO now.
- System for dynamically adding new SEXPs. With this a Lua script can expose functionality to the mission which can be used exactly the same as a standard SEXP with all the usual editing features in FRED.   
- Support for displaying decals on the surface of an object.
- Integrated support for the [Discord Rich Presence API](https://discordapp.com/rich-presence). 
- New markup based user interface system using [libRocket](https://github.com/libRocket/libRocket).
-### Changed
- Exposed the movie player to the scripting API for advanced display features
- Various OpenGL optimizations for better graphics performance:
-  - Animations now use texture arrays
-  - Model uniforms get sent to the GPU using uniform buffers for less overhead
-  - Various other minor changes
- Converted pilot files from custom binary format to JSON
- Replaced Blinn-Phong BRDF with GGX BRDF
-### Fixed
- Refactored bitmap slot handling and removed the fixed upper limit on the number of bitmaps. No more bmpman corruption!
-
-## [3.8.0] - 2017-08-22 ([Release Thread](https://www.hard-light.net/forums/index.php?topic=93812.0))
-### Added
- Support for APNG animations: [APNG](https://en.wikipedia.org/wiki/APNG) is a variant of the established PNG format which allows to store animations instead of single frames in a PNG file. This change allows to use these animation files in FSO which significantly improves usability for modders since they no longer have to store all individual frames as separate images.
- Physically-Based Rendering (PBR): This upgrade of our rendering engine allows to use [PBR](https://en.wikipedia.org/wiki/Physically_based_rendering) assets to make models look more realistic and allow more artistic freedom for modders since they have more control over how a model looks. This also added support for HDR lighting which should improve the overall graphics experience.
- Native particle systems: Particles have always been supported by FSO but the effects that could be created by them were very limited. There were some attempts to fix this by using Lua scripting for more advanced features but that suffered from performance issues. With these new particle systems that feature has been integrated directly into the engine which should improve performance and allow for better effects in the future.
- TrueType Font support: [TrueType](https://en.wikipedia.org/wiki/TrueType) fonts improve the text rendering capabilities of FSO by allowing to use freely scaleable font faces instead of the previous bitmap fonts.
-### Changed
- We now use SDL2 on all platforms: SDL is a library for abstracting away the differences between different platforms. We now use SDL2 for all platforms which reduces the amount of platform-specific code tremendously and should result in better usability on all platforms. This was a major change that has been in development for several years. Here are a few key features that were added:
-  - Pilot and configuration data is now stored in the correct location across all platforms (this allows to run FSO on Windows from the Program Files directory without administrator rights)
-  - All platforms now use the ini files for storing settings. This fixes a lot of issues with the registry on Windows.
-  - Better support for input devices. Since SDL handles keyboard, mouse and joystick input we now have better support on newer OS versions. Note: This does not mean that we support multiple joysticks (yet). There is ongoing development effort to support this but this release does not have that yet.
- CMake build system generation: This isn't relevant for players but we are now using [CMake](https://en.wikipedia.org/wiki/CMake) for handling compiling our builds. This improves cross-platform support and allows to implement advanced compilation features across multiple platforms. Modders will like the new "FastDebug" builds which are like the previous "Debug" builds but are compiled with all the optimizations of normal Release builds. That should make modding a lot easier since you can now debug your mod with almost the same performance as a Release build.
- Improved shield effects: Rendering of the shields is now handled by special shaders which improves the overall quality of the effects and allows more freedom for future effects.
- Use OpenGL Core Profile for rendering: This is another major graphical upgrade which adds support for the OpenGL Core profile across all platforms (this was also made possible by the SDL2 integration). This upgrade allows us to use more modern rendering techniques and is especially useful for our Linux users who use the open-source Mesa drivers since our shaders failed to compile with those drivers. Now everyone will be able to enjoy the new graphical features added in this and previous releases. This also made some internal changes to how we handle rendering which improves the usability of our rendering engine within our code.
- Use FFmpeg for video & audio decoding: [FFmpeg](https://www.ffmpeg.org/) is a multi-media library which exposes functionality for decoding video and audio files to their raw form so that we can use that data. Thanks to this library we can now play 1080p cutscenes without any stuttering or frame-timing issues. It also allows to use more advanced audio and video codecs such as H.264 for video or Opus for audio.

 Building
 --
 Before you do anything, make sure you have updated your git submodules, either by running `git submodule update --init --recursive` or by cloning the repository with the `--recursive` flag.<br/>
+<br/>
+For building you will need [CMake](http://www.cmake.org/cmake/resources/software.html). Version 3.4 is required. Once you have installed CMake you should create a build directory where the project/make files should be created, **do not create them inside the source tree!**<br>
+<br>
+On Windows you can use the `cmake-gui` executable to get a nice GUI, on Unix just use `cmake`. Use the newly created directory as build directory (change to this directory on Unix) and run cmake. On Windows this can be done by clicking the `Configure` button. Choose your compiler version and hit `Generate` when configuring is done. <br>
+Depending on the makefile generator used build the `all` or `ALL_BUILD` target to compile the project.<br>

-The main instructions for building can be found at our github wiki, on the [Building](https://github.com/scp-fs2open/fs2open.github.com/wiki/Building) page.
+### Available variables to control the build
+* `FSO_BUILD_WXFRED2`: Build the wxfred2 project, requires wxWidgets
+* `FSO_FREESPACE_PATH`: Sets the path of your FreeSpace install, can be used to automatically run the generated executables with the correct working directory, this is an optional variable. By default this will use the value of the `FS2PATH` environment variable.
+* `FSO_BUILD_TOOLS`: Build some tools related to FSO
+* `CMAKE_BUILD_TYPE`: Sets the binary build type between `Debug` and `Release` (default)
+
+#### Windows only variables
+* `FSO_BUILD_FRED2`: Build FRED2, requires a Visual Studio version that ships with MFC
+* `FSO_USE_SPEECH`: Build a binary with text-to-speech support
+* `FSO_USE_VOICEREC`: Build a binary with voice recognition support
+
+#### Advanced variables
+You should only use these variables if you know what you're doing
+* `FSO_CMAKE_DEBUG`: Print CMake debugging informations
+* `FSO_BUILD_INCLUDED_LIBS`: Build libraries from the included source
+* `FSO_USE_OPENALSOFT`: Use [OpenALSoft](http://kcat.strangesoft.net/openal.html) for OpenAL support
+* `FSO_USE_LUAJIT`: Use [luajit](http://luajit.org/) as a replacement for lua
+* `FSO_DEVELOPMENT_MODE`: Toggles some development behavior, only use if you really need it.
+* `FSO_RUN_ARGUMENTS`: If you run an executable from within the project, these arguments will also be passed to the executable
+* `FSO_BUILD_POSTFIX`: Sets a postfix to be added to the executable name, may be useful for release candidates.
+
+#### Visual Studio specific variables
+* `MSVC_USE_RUNTIME_DLL`: Use the DLL version of the runtime, experimental and not well tested.
+* `MSVC_SIMD_INSTRUCTIONS`: The instruction set the executables will be optimized for.
+
+### Generating an installation package
+CMake can automatically generate installation packages of the project. To do this you will just need to run the `package` target of the build system and the package will be placed inside your build directory. On Windows you will have to install [NSIS](http://nsis.sourceforge.net/Main_Page) to use this.

-#Updating Documentation
-####The goal of this file is simply to offer a comprehensive checklist of things we must check when updating the documentation.
-
-1. Changelog: 
- - Is [Changelog.md](https://github.com/scp-fs2open/fs2open.github.com/blob/master/Changelog.md) up-to-date with the latest release?
- - Is it in the proper [Keep a Changelog](https://keepachangelog.com/en/1.0.0/) format? 
-2. Build instructions:  
- - If a programmer who never built FSO before read the build instruction at [Readme.md](https://github.com/scp-fs2open/fs2open.github.com/blob/master/Readme.md), would they manage to build FSO? 
- - Is the information in the file up-to-date regarding other matters (such as versions of tools mentioned, links to other guides, etc.)?
- - Is the information in the [Building](https://github.com/scp-fs2open/fs2open.github.com/wiki/Building) article, and its sub-articles, still up-to-date?
-3. Forums: 
- - Does the [Forum](https://www.hard-light.net/forums/index.php?board=50.0) contain enough clear information to help a new developer find their way into the up-to-date instructions?
- - Is there anything that might mislead a new developer to stumble onto old tools, dead links and/or old versions of the project?
-4. General documentation files: 
- - Is the information in the following files up-to-date? 
-   - [About.md](https://github.com/scp-fs2open/fs2open.github.com/blob/master/About.md) (Should contain general information about FS, FS2, HLP, FSO and FSU)
-   - [Authors.md](https://github.com/scp-fs2open/fs2open.github.com/blob/master/Authors.md) (Should contain information about the original developers, a way to see FSO's contributors, and special thanks to Volition and Dave Baranec)
-   - [Copying.md](https://github.com/scp-fs2open/fs2open.github.com/blob/master/Copying.md) (Should contain Volition's Copyright terms and a way to check FSO's Licensing info)
