## What it is
A web application that shows the exact file diffs between any two React Native versions to guide app upgrades. It is built on the rn-diff-purge project, which generates clean diffs from freshly initialized React Native apps for each release.

## Use cases
- upgrade my React Native app to a newer version
- see what files changed between two React Native releases
- diff my project against a fresh React Native init template
- figure out which config files to update when upgrading React Native
- track progress while migrating React Native versions

## When to choose
- you are upgrading a React Native app and need to know exactly which files to change
- you want version-specific upgrade guidance with inline comments and helpful links
- you prefer a visual diff over manually running upgrade commands

## When to avoid
- you are not working with React Native
- you want a fully automated upgrade tool rather than a manual diff reference
- you need to upgrade dependencies other than React Native itself
