-## `userEvent.setup`
+This means that we plan to keep the public API signatures to remain stable, but we might introduce breaking behavioural changes, e.g. changing the ordering or timing of emitted events, without a major version update. Hopefully, well written code should not rely on such specific details.
+:::
+
+## Comparison with Fire Event API
+
+Fire Event is our original event simulation API. It offers ability to invoke **any event handler** declared on **either host or composite elements**. If the element does not have `onEventName` event handler for passed `eventName` event, or the element is disabled, Fire Event will traverse up the component tree, looking for event handler on both host and composite elements along the way. By default it will **not pass any event data**, but the user might provide it in the last argument.
+
+In contrast, User Event provides realistic event simulation for main user interactions like `press` or `type`. Each of the interactions will trigger a **sequence of events** corresponding to React Native runtime behavior. These events will be invoked **only on host elements**, and **will automatically receive event data** corresponding to each event.
+
+If User Event supports given interaction you should always prefer it over Fire Event counterpart, as it will make your tests much more realistic and hence reliable. In other cases, e.g. when event is not supported by User Event, or when invoking event handlers on composite elements, you have to use Fire Event as the only available option.

 Simulates a long press user interaction. In React Native the `longPress` event is emitted when the press duration exceeds long press threshold (by default 500 ms). In other aspects this actions behaves similar to regular `press` action, e.g. by emitting `pressIn` and `pressOut` events. The press duration is customisable through the options. This should be useful if you use the `delayLongPress` prop. When using real timers this will take 500 ms so it is highly recommended to use that API with fake timers to prevent test taking a long time to run.
