+**Unreal Engine GPU Point Cloud Renderer**
+
+This is a GPU-based Plugin for Real-Time rendering of dynamic and massive point cloud data in Unreal. This project is still under development and not (yet) a finalised plugin.
+
+__This plugin is only for rendering point clouds and does NOT load point cloud files or visualise Kinect data.__
+__For loading PCD files, processing point clouds with PCL or fetching data from a Kinect, another plugin will follow soon.__
+
+Currently supported Unreal Versions:
+* __UE4.21__
+* UE4.19 (see other branch)
+
+The ComputeShader-powered version for proper in-place depth-ordering of the points is still in development (see other branch).
