 # Storage-py
 
 Python Client library to interact with Supabase Storage.
+
+
+
+## How to use
+
+As it takes some effort to get the headers. We suggest that you use the storage functionality through the main [Supabase Python Client](https://github.com/supabase-community/supabase-py)
+
+
+```python3
+from storage3 import storage_client
+
+storage_client = storage_client.SupabaseStorageClient('https://<your_supabase_id>.supabase.co/storage/v1)', {'apiKey': '<your_api_key>', 'Authorization': 'Bearer <an_auth_token>'})
+
+storage_client.list()
+```
