# Markdown Reader (Async)

The **Markdown Reader** with asynchronous processing allows you to handle Markdown files efficiently and integrate them with knowledge bases.

## Code

```python examples/concepts/knowledge/readers/markdown_reader_async.py theme={null}
import asyncio
from pathlib import Path

from agno.agent import Agent
from agno.knowledge.knowledge import Knowledge
from agno.vectordb.pgvector.pgvector import PgVector

db_url = "postgresql+psycopg://ai:ai@localhost:5532/ai"

knowledge = Knowledge(
    vector_db=PgVector(
        table_name="markdown_documents",
        db_url=db_url,
    ),
    max_results=5,  # Number of results to return on search
)

agent = Agent(
    knowledge=knowledge,
    search_knowledge=True,
)

if __name__ == "__main__":
    asyncio.run(
        knowledge.add_content_async(
            path=Path("README.md"),
        )
    )

    asyncio.run(
        agent.aprint_response(
            "What can you tell me about Agno?",
            markdown=True,
        )
    )
```
