-# THIS REPOSITORY HAS BEEN DEPRECATED
+# Kokkos NVCC Wrapper
+
+This wraps an nvcc, allowing it to be treated as a real C++ compiler with all the usual flags.
+Simple run `cmake` as usual to configure the compiler. The only two flags that need to be set are:
+````
+-DCMAKE_CXX_COMPILER=
+-DCMAKE_CUDA_COMPILER=
+````
+so that the wrapper knows which underlying `nvcc` and which underlying `g++` to use.
+This is configured as both a CXX and CUDA project with CMake, which means a valid
+CUDA installation must be available.
 
-Use `bin/nvcc_wrapper` from [kokkos/kokkos](https://github.com/kokkos/kokkos) instead
