+As [react-navigation](https://reactnavigation.org) is alo undergoing development and possible API changes, this library provides a testing ground and working API for the v3 branch of react-navigation (**UPDATE: Also works with v4)**.
 It was written as a separate library which does not require any changes to react-navigation itself.
 As time progresses, the goal is to support the latest react-navigation version, support `appear` and `disappear` transitions, and have the 
 [native extensions](https://github.com/IjzerenHein/react-native-shared-element) land in [Expo](https://expo.io/).

-### SharedElementConfig
+### sharedElements config
 
 In order to trigger shared element transitions between screens, a static `sharedElements` config needs to be defined on one of the two screens. For
 each screen transition, both screens are evaluated and checked whether they have a `sharedElements` config. The screen that is being shown is **evaluated first**, followed by the screen that is being hidden. If `undefined` is returned, evaluation continues at the other screen.
