+# CK Tile Dispatcher Python Utilities
+
+This directory contains Python utilities used by the dispatcher examples.
+
+## Contents
+
+- `ctypes_utils.py` - Core ctypes utilities for GEMM Python examples
+  - `KernelConfig` - Kernel configuration dataclass
+  - `setup_gemm_dispatcher()` - Setup dispatcher with auto-correction
+  - `cleanup_gemm()` - Cleanup dispatcher resources
+  - `GemmRunner` - GPU execution helper
+  - Auto-correction and validation utilities
+
+- `conv_utils.py` - Core utilities for Conv Python examples
+  - `ConvSignature`, `ConvAlgorithm` - Convolution configuration
+  - `ConvProblem` - Problem definition
+  - `GpuConvRunner` - GPU execution helper
+  - `EnhancedConvCodegenRunner` - Kernel codegen utilities
+
+## Usage
+
+### GEMM Examples
+
+The GEMM Python examples in `dispatcher/examples/gemm/python/` import:
+
+```python
+import sys
+from pathlib import Path
+sys.path.insert(0, str(Path(__file__).parent.parent.parent.parent / "python"))
+
+from ctypes_utils import (
+    KernelConfig,
+    setup_gemm_dispatcher,
+    cleanup_gemm,
+    GemmRunner,
+)
+```
+
+### Conv Examples
+
+The Conv Python examples in `dispatcher/examples/conv/python/` import:
+
+```python
+import sys
+from pathlib import Path
+sys.path.insert(0, str(Path(__file__).parent.parent.parent.parent / "python"))
+
+from conv_utils import (
+    ConvSignature,
+    ConvAlgorithm,
+    ConvProblem,
+    GpuConvRunner,
+)
+```
+
+## Requirements
+
+- Python 3.8+
+- NumPy
+- HIP runtime (for GPU execution)
