 ### Best practices
 
 Another purpose of this app is to define best practices such as the folder structure of a standalone React Native app and naming conventions.
 
 ## Not using Redux
 
-This template intentionally doesn't use Redux. After discussing with a few people who have experience using Redux we concluded that adding Redux to this app targeted at beginners would make the code more confusing, and wouldn't clearly show the benefits of Redux (because the app is too small). There are already a few concepts to grasp - the React component lifecycle, rendeing lists, using async / await, handling the software keyboard. We thought that's the maximum amount of things to learn at once. It's better for everyone to see patterns in their codebase as the app grows and decide for themselves whether and when they need Redux.
