+## Connection String
+
+Required:
+
+- Schema
+- Initial server address
+- port number (default 7687)
+
+schemas:
+
+- neo4j creates an unencrypted connection
+- neo4j+s creates an encrypted connection and verifies certificate
+- neo4j+ssc - Creates an encrypted connection no verification certificate
+
+Variations of the bolt scheme can be used to connect directly to a single DBMS (within a clustered environment or standalone). This can be useful if you have a single server configured for data science or analytics.
+
+- bolt creates an unencrypted connection directly to a single DBMS.
+- bolt+s creates an encrypted connection directly to a single DBMS and verify the certificate.
+- bolt+ssc creates an encrypted connection to directly to a single DBMS but will not attempt to verify the authenticity of the certificate.
+
+**Which scheme string is right?**
+
+You can verify the encryption level of your DBMS by checking the dbms.connector.bolt.enabled key in neo4j.conf.
+
+Always use the neo4j+s scheme when connecting to Neo4j Aura
+
+## Authentication Token
+
+```python
+auth = (username, password)
+```
+
+## Additional Driver Configuration (Optional)
+
+Example
+
+```python
+GraphDatabase.driver(uri, auth=auth,
+    max_connection_lifetime=30 * 60,
+    max_connection_pool_size=50,
+    connection_acquisition_timeout=2 * 60)
+```
