+Schema Validation
+-----------------
+
+ArangoDB supports document validation using JSON schemas. You can use this
+feature by providing a schema during collection creation using the ``schema``
+parameter.
+
+**Example:**
+
+.. testcode::
+
+    from arango import ArangoClient
+
+    # Initialize the ArangoDB client.
+    client = ArangoClient()
+
+    # Connect to "test" database as root user.
+    db = client.db('test', username='root', password='passwd')
+
+    # Create a new collection named "employees".
+    if db.has_collection('employees'):
+        db.delete_collection('employees')
+
+    employees = db.create_collection(
+        name='employees',
+        schema={
+            'rule': {
+                'type': 'object',
+                'properties': {
+                    'name': {'type': 'string'},
+                    'email': {'type': 'string'}
+                },
+                'required': ['name', 'email']
+            },
+            'level': 'moderate',
+            'message': 'Schema Validation Failed.'
+        }
+    )
