+# Get Started with Microsoft Agent Framework Durable Functions
+
+[![PyPI](https://img.shields.io/pypi/v/agent-framework-azurefunctions)](https://pypi.org/project/agent-framework-azurefunctions/)
+
+Please install this package via pip:
+
+```bash
+pip install agent-framework-azurefunctions --pre
+```
+
+## Durable Agent Extension
+
+The durable agent extension lets you host Microsoft Agent Framework agents on Azure Durable Functions so they can persist state, replay conversation history, and recover from failures automatically.
+
+### Basic Usage Example
+
+See the durable functions integration sample in the repository to learn how to:
+
+- Register agents with `AgentFunctionApp`
+- Post messages using the generated `/api/agents/{agent_name}/run` endpoint
+
+For more details, review the Python [README](https://github.com/microsoft/agent-framework/tree/main/python/README.md) and the samples directory.
