+
+![OffAxisExample](https://github.com/fweidner/UE4-Plugin-OffAxis/blob/master/2018-06-13.gif)
+
+## Current version
+Works with 4.22 :)
+
+## General info: 
+It works. But it is (always) experimental :)
+
+* OffAxisProjection / FishTank VR
+** in 2D Mode: OffAxisActor can be placed arbitrarily.
+** in 3D Mode: OffAxisActor can be placed parallel to the Z-Y-Plane and rotated using pitch and roll.
+* Also shows one possibility of how to modify the projection matrix. 
+
+## How to use:
+Assuming you start with a Basic Code C++ project:
+- Update LocalPlayer class in Edit->Project Settings->General Settings 
+- Adjust Input mappings to your Config/DefaultInput.ini
+- Drag the OffAxisActor in your scene
+- Set position of OffAxisActor to 0,0,0
+- In the OffAxisActor, place the child actors P_a, P_b, and P_c so that the correspond to the corners of your "virtual window".
+- Change your NearClippingPlane .1f 
+
+## Input Mappings
+Restart after updating DefaultInput.ini!
