+## Options
+
+This rule provides the following options:
+
+- `eventModules`: array of strings. The possibilities are: `"fire-event"` and `"user-event"`. Defaults to `["fire-event", "user-event"]`
+
+### `eventModules`
+
+This option gives you more granular control of which event modules you want to report, so you can choose to only report methods from either `fire-event`, `user-event` or both.
+
+Example:
+
+```json
+{
+  "testing-library/no-await-sync-events": [
+    "error",
+    {
+      "eventModules": ["fire-event", "user-event"]
+    }
+  ]
+}
 ```
 
 ## Notes
 
-There is another rule `await-fire-event`, which is only in Vue Testing
-Library. Please do not confuse with this rule.
+- Since `user-event` v14 all its methods are async, so you should disable reporting them by setting the `eventModules` to just `"fire-event"` so `user-event` methods are not reported.
+- There is another rule `await-fire-event`, which is only in Vue Testing
+  Library. Please do not confuse with this rule.
