 * Call OrtAddCustomOpDomain to add the custom domain of ops to the session options
 See [this](../onnxruntime/test/shared_lib/test_inference.cc) for an example called MyCustomOp that uses the C++ helper API (onnxruntime_cxx_api.h).
 You can also compile the custom ops into a shared library and use that to run a model via the C++ API. The same test file contains an example.
-The source code for a sample custom op shared library containing two custom kernels is [here](..onnxruntime/test/testdata/custom_op_library/custom_op_library.cc).
+The source code for a sample custom op shared library containing two custom kernels is [here](../onnxruntime/test/testdata/custom_op_library/custom_op_library.cc).
 See [this](../onnxruntime/test/python/onnxruntime_test_python.py) for an example called testRegisterCustomOpsLibrary that uses the Python API
 to register a shared library that contains custom op kernels.
 Currently, the only supported Execution Providers (EPs) for custom ops registered via this approach are the `CUDA` and the `CPU` EPs.
