+# Multiagent Concurrent
+
+This example demonstrates how to run multiple agents concurrently in AgentScope, where each agent operates
+independently and can perform tasks simultaneously.
+
+Specifically, we showcase two ways to achieve concurrency:
+
+- Using Python's `asyncio.gather` to run multiple agents asynchronously.
+- Using `fanout_pipeline` to execute multiple agents in parallel and gather their results.
+
+The fanout pipeline will distribute the input to multiple agents and collect their outputs, which is appropriate for
+scenarios like voting or parallel question answering.
+
+## QuickStart
+
+Install the agentscope package if you haven't already:
+
+```bash
+pip install agentscope
+```
+
+Then run the example script:
+
+```bash
+python main.py
+```
