 ## Execution Provider Shared Libraries
 
-The oneDNN, TensorRT, OpenVINO™, and CANN providers are built as shared libraries vs being statically linked into the main onnxruntime. This enables them to be loaded only when needed, and if the dependent libraries of the provider are not installed onnxruntime will still run fine, it just will not be able to use that provider. For non shared library providers, all dependencies of the provider must exist to load onnxruntime.

+### Build Options
+{: .no_toc }
+
+* `--use_qnn [QNN_LIBRARY_KIND]`: Builds the QNN Execution provider. `QNN_LIBRARY_KIND` is optional and specifies whether to build the QNN Execution Provider as a shared library (default) or static library.
+  * `--use_qnn` or `--use_qnn shared_lib`: Builds the QNN Execution Provider as a shared library.
+  * `--use_qnn static_lib`: Builds QNN Execution Provider as a static library linked into ONNX Runtime. This is required for Android builds.
+* `--qnn_home QNN_SDK_PATH`: The path to the Qualcomm AI Engine Direct SDK.
+  * Example on Windows: `--qnn_home 'C:\Qualcomm\AIStack\QAIRT\2.31.0.250130'`
+  * Example on Linux: `--qnn_home /opt/qcom/aistack/qairt/2.31.0.250130`
+* `--build_wheel`: Enables Python bindings and builds Python wheel.
+* `--arm64`: Cross-compile for ARM64.
