+# Adding external agents to the crew
+
+This example shows how you can add external agents to the crew, on the example of a langchain agent.
+
+You do this by inheriting from the `AgentWrapperParent` class and implementing its abstract methods.
+
+These agents can then be mixed and matched with native CrewAI agents.
+
+An implementation for langchain agent is already provided and can be used as in the following example:
+
+    ```python
+    from langchain import hub
+    from langchain.agents import create_openai_tools_agent
+    from langchain_openai import ChatOpenAI
+    from langchain_community.tools import DuckDuckGoSearchRun
+    
+    from crewai.agents.langchain_agent import LangchainCrewAgent
+    
+    llm = ChatOpenAI(model="gpt-4-0125-preview", temperature=0)
+    tools = [DuckDuckGoSearchRun()]    
+    researcher_prompt = hub.pull("hwchase17/openai-tools-agent")
+
+    researcher_agent = AgentExecutor(
+        agent=create_openai_tools_agent(llm, tools, researcher_prompt),
+        tools=tools,
+        verbose=True,
+    )
+    
+    researcher = LangchainCrewAgent(
+        agent=researcher_agent,
+        tools=[search_tool],
+        role="Senior Research Analyst",
+        allow_delegation=False,
+    )
+
+You need to pass a function that creates the desired agent from the list of its tools, to enable adding other agents as tools at runtime (for delegation).
