+| 1.22         | 1.0          | 12.8           |
+
+### Pre-requisites
+* Install git, cmake, Python 3.12
+* Install latest [NVIDIA driver](https://www.nvidia.com/en-us/drivers/)
+* Install [CUDA toolkit 12.9](https://developer.nvidia.com/cuda-12-9-1-download-archive)
+* Install [TensorRT RTX](https://docs.nvidia.com/deeplearning/tensorrt-rtx/latest/installing-tensorrt-rtx/installing.html)
+* For Windows only, install [Visual Studio](https://visualstudio.microsoft.com/downloads/)
+* Set TensorRT-RTX dlls in `PATH` or put it in same folder as application exe
+
+

 ### Build Instructions
@@ -235,20 +292,7 @@ These instructions are for the latest [JetPack SDK](https://developer.nvidia.com
 
 * For a portion of Jetson devices like the Xavier series, higher power mode involves more cores (up to 6) to compute but it consumes more resource when building ONNX Runtime. Set `--parallel 1` in the build command if OOM happens and system is hanging.
 
-## TensorRT-RTX
-
-See more information on the NV TensorRT RTX Execution Provider [here](../execution-providers/TensorRTRTX-ExecutionProvider.md).

-### Prerequisites
-{: .no_toc }
-
- * Follow [instructions for CUDA execution provider](#cuda) to install CUDA and setup environment variables.
- * Intall TensorRT for RTX from nvidia.com (TODO: add link when available)
