+# Custom Kernel using MIGraphX API. 
+This is an example of a custom operator implementation using MIGraphX's C/C++ APIs. It also demonstrates how to use this custom op in conjunction with rest of MIGraphX operators to build  and run MIGraphX program on GPU. 
+
+Kernels can be written in either HIP, MIOpen, or by using RocBLAS library. This particular example uses **HIP**.
+
+ To build the example, ensure ROCm is installed at `/opt/rocm`.
