 A C++ library for the amazing [WaveFunctionCollapse](https://github.com/mxgmn/WaveFunctionCollapse) algorithm, plus various utilities for running it.
-Finally, there is an Unreal 5 plugin to integrate the `Tiled3D` part of the library with Unreal Engine.
+There is also [an Unreal 5 plugin](https://github.com/heyx3/WfcUnreal) (WIP) to integrate the `Tiled3D` module with Unreal Engine.
 
 For more explanation of the algorithm itself, you can read this project's source or check out [EasyWFC](https://github.com/heyx3/EasyWFC), whose behavior should be identical to this project (except for the PRNG).
 
- The core library has a "Simple" version (for pixel art images), a "tiled" version (for tile-sets), and a "tiled 3D" version (for 3D tile-sets).
- The first two systems have corresponding command-line programs for playing with them.
- The 3D tile-set system is more complex and offers Unreal Engine 5 integration.

 ## Setup
 
 After cloning the repo, just open **WFC++.sln** in Visual Studio, set the platform to **x64**, and build. You may want to change the "startup project" to one of the command-line apps, if that's what you want to use.
 
 ## Structure
 
-The project has one Visual C++ solution with four projects, plus an Unreal Engine 4 project:

 ### WFC++
 
-The actual algorithm code is in the WFC++ project. When built, it creates the .dll, .lib, and .h/.hpp files in the "Build" folder.
+The *WFC++* project contains the actual algorithm code.

 The code files are split into the following categories, all of which are inside the `WFC` namespace:

-This is an old version of the Unreal plugin, for UE4 and very unpolished (though it should work!)

 Unit tests use the *UnitTest++*"* library, kept in the folder 'UnitTestLibrary'.
