+
+The `onnx_ir.external_data` module provides utilities for handling external data in ONNX models. It enables the conversion of tensors to and from external data files, allowing for efficient storage and manipulation of large tensor data. This is particularly useful for models with large initializers that exceed memory constraints.

+## Use built-in passes
+
+Common, reusable passes are implemented in `onnx_ir.passes.common`. You can use {py:class}`onnx_ir.passes.Sequential <onnx_ir.passes.Sequential>` to chain passes or use {py:class}`onnx_ir.passes.PassManager <onnx_ir.passes.PassManager>` which supports early stopping if no changes are made.
+
+## Pass infrastructure
+
+Inherent {py:class}`onnx_ir.passes.InPlacePass <onnx_ir.passes.InPlacePass>` or {py:class}`onnx_ir.passes.FunctionalPass <onnx_ir.passes.FunctionalPass>` to define a pass. You will need to implement the `call` method which returns a {py:class}`onnx_ir.passes.PassResult <onnx_ir.passes.PassResult>`.
+
+Alternatively, inherent the base class `onnx_ir.passes.PassBase <onnx_ir.passes.PassBase>` and override the two properties `changes_input` and `in_place` to set properties of the pass.
