+Per-route request timeouts
+--------------------------
+
+Different API operations may need different timeouts during testing. You could achieve it this way:
+
+.. code-block:: python
+
+    import schemathesis
+
+    DEFAULT_TIMEOUT = 10  # in seconds
+    SCHEMA_URL = "http://localhost/schema.json"
+    schema = schemathesis.from_uri(SCHEMA_URL)
+
+
+    @schema.parametrize()
+    def test_api(case):
+        key = (
+            case.operation.method.upper(),
+            case.operation.path,
+        )
+        timeout = {
+            ("GET", "/users"): 5,
+            # and so on
+        }.get(key, DEFAULT_TIMEOUT)
+        case.call_and_validate(timeout=timeout)
+
+In the example above, the default timeout is 10 seconds, but for `GET /users` it will be 5 seconds.
