 ### What's unique about Detox
 
-**Synchronization**
+#### Synchronization
 
 One of the key features that makes Detox unique is that it synchronizes with app state, so it can know when to move to the next step of a test, instead of including manual sleep statements. [See the documentation for more info](https://wix.github.io/Detox/docs/articles/how-detox-works/#how-detox-automatically-synchronizes-with-your-app).
 
 But this does create new kinds of errors to be aware of. For example, if you see a Detox test hanging, that's an indication that Detox might not be detecting that the app went into the idle state so that the test can continue. To debug, check out [Detox's troubleshooting guide on sync issues](https://wix.github.io/Detox/docs/troubleshooting/synchronization).
