-## Guiding principles
-
-> [The more your tests resemble the way your software is used, the more confidence they can give you.](https://twitter.com/kentcdodds/status/977018512689455106)
-
-We try to only expose methods and utilities that encourage you to write tests that closely resemble
-how your apps are used.
-
-Utilities are included in this project based on the following guiding principles:
-
-1.  Rendering React Native components ultimately creates native views, and those views should be
-    what you test rather than the React component instances you rendered to make them.
-2.  In general, test the way your users use your app. There are instances where you'll need to write
-    unit tests, but try your best to write with this first -- the more your tests resemble the way
-    your app works, the more confident you'll be with your app.
-3.  Be responsible, and remember that testing exists to serve you, not the other way around. If the
-    library isn't working for you, contribute to make it work or do something more intuitive. Make
-    your tests work for you and your team!
-
-In summary, we believe in the principles of `dom-testing-library` and its companion libraries, and
-try to adhere to them as closely as possible. Changes to this library should always consider how
-they relate to what's happening in the other libraries in this family of tools.

 ## Hooks
 
-You can test hooks out of the box with this package as follows:
-
-```javascript
-import { renderHook } from 'native-testing-library';

-## Inspiration
-
-Huge thanks to Kent C. Dodds for evangelizing this approach to testing. We could have never come up
-with this library without him 🙏. Check out his awesome work and learn more about testing with
-confidence at [testingjavascript.com](https://testingjavascript.com/) (you won't regret purchasing
-it), and of course, use this library's big brother, `react-testing-library` for your DOM
-applications as well!
-
-The hook testing ability of this library is the same implementation as
-[react-hooks-testing-library](https://github.com/mpeyper/react-hooks-testing-library). The only
-reason it was included in this package is because we need you to import render from us, not the
-`dom-testing-library`, and that's an important blocker. Some day, maybe we'll try to allow use of
-that library with this one somehow.
