+### Referencing Sources
+
+You can reference knowledge sources by their collection name or metadata.
+
+* Add a directory to your crew project called `knowledge`:
+* File paths in knowledge can be referenced relative to the `knowledge` directory.
+
+Example:
+A file inside the `knowledge` directory called `example.txt` can be referenced as `example.txt`.
+
+```python
+source = TextFileKnowledgeSource(
+    file_path="example.txt", # or /example.txt
+    collection_name="example"
+)
+crew = Crew(
+    agents=[agent],
+    tasks=[task],
+    knowledge_sources=[source],
