# Wikipedia Reader

The **Wikipedia Reader** allows you to search and read Wikipedia articles synchronously, converting them into vector embeddings for your knowledge base.

## Code

```python examples/concepts/knowledge/readers/wikipedia_reader_sync.py theme={null}
from agno.agent import Agent
from agno.knowledge.knowledge import Knowledge
from agno.knowledge.reader.wikipedia_reader import WikipediaReader
from agno.vectordb.pgvector import PgVector

# Create Knowledge Instance
knowledge = Knowledge(
    name="Wikipedia Knowledge Base",
    description="Knowledge base from Wikipedia articles",
    vector_db=PgVector(
        table_name="wikipedia_vectors", 
        db_url="postgresql+psycopg://ai:ai@localhost:5532/ai"
    ),
)

# Add topics from Wikipedia synchronously
knowledge.add_content(
    metadata={"source": "wikipedia", "type": "encyclopedia"},
    topics=["Manchester United", "Artificial Intelligence"],
    reader=WikipediaReader(),
)

# Create an agent with the knowledge
agent = Agent(
    knowledge=knowledge,
    search_knowledge=True,
)

# Query the knowledge base
agent.print_response(
    "What can you tell me about Manchester United?",
    markdown=True
)
```
