+# Upgrade React Native
+
+Upgrade a React Native Community CLI project to a target version by fetching
+and applying the diff from the
+[React Native Upgrade Helper](https://react-native-community.github.io/upgrade-helper/).
+
+## Invocation
+
+```
+/upgrade-react-native <targetVersion>
+```
+
+- `<targetVersion>` — the React Native version to upgrade to (e.g. `0.79.0`).
+
+## Step-by-step procedure
+
+Follow every step below **in order**. Do not skip steps.
+
+### 1. Detect the current React Native version
+
+Read the project's root `package.json` and extract the `react-native` version
+from `dependencies` (or `devDependencies`). Strip any semver range prefix
+(`^`, `~`, `>=`, etc.) to get the exact current version string.
+
+If the current version cannot be determined, stop and ask the user.
+
+### 2. Validate the target version
+
+- The target version must be a valid semver string (e.g. `0.79.0`).
+- It must be **greater than** the current version.
+- Verify the target version exists by checking:
+  ```
+  https://raw.githubusercontent.com/react-native-community/rn-diff-purge/master/RELEASES
+  ```
+  Fetch this file and confirm the target version is listed. If not, report the
+  closest available versions and ask the user to choose.
+
+### 3. Fetch the upgrade diff
+
+Fetch the unified diff between the two versions:
+
+```
+https://raw.githubusercontent.com/react-native-community/rn-diff-purge/diffs/diffs/<currentVersion>..<targetVersion>.diff
+```
+
+For example, to upgrade from `0.73.0` to `0.74.0`:
+
+```
+https://raw.githubusercontent.com/react-native-community/rn-diff-purge/diffs/diffs/0.73.0..0.74.0.diff
+```
+
+If the diff cannot be fetched (404), it may be because exact patch versions are
+not available. Try the nearest minor versions (e.g. `0.73.0` instead of
+`0.73.2`). Report what you tried and ask the user if needed.
+
+### 4. Parse the diff and map file paths
+
+The diff uses the template project name `RnDiffApp`. Map every path in the diff
+to the actual project:
+
+| Diff path prefix | Actual project path |
+|------------------|---------------------|
+| `RnDiffApp/` | Project root (`./`) |
+
+Additionally, replace occurrences of the template identifiers with the project's
+actual names:
+
+| Template value | Replace with |
+|----------------|--------------|
+| `RnDiffApp` | The project's app name (from `app.json` → `name`, or the `name` field in `package.json`) |
+| `rndiffapp` | Lowercase version of the project's app name |
+| `com.rndiffapp` | The project's Android package name (from `android/app/build.gradle` or `android/app/src/main/AndroidManifest.xml`) |
+
+### 5. Review the diff and plan changes
+
+Before making any edits, review the entire diff and categorize changes:
+
+1. **Direct applies** — files that exist in the project and whose original
+   content matches the diff's `-` lines. These can be applied as-is.
+2. **Conflicts** — files where the project's content has diverged from the
+   template (custom modifications). These need manual merging.
+3. **New files** — files in the diff that don't exist in the project yet. Create
+   them.
+4. **Deleted files** — files the diff removes. Delete them only if the project
+   hasn't added custom content to them.
+
+Present this plan to the user before proceeding. Group changes by area:
+
+- **Root config files** (`package.json`, `metro.config.js`, `.eslintrc.js`, etc.)
+- **iOS native files** (`ios/` directory)
+- **Android native files** (`android/` directory)
+- **JavaScript/TypeScript source** (if any template source files changed)
+- **Third-party native dependencies** (from step 7 — include any version bumps
+  identified there)
+
+### 6. Apply changes
+
+Apply the changes following the plan from step 5:
+
+- For **direct applies**: edit the file to match the diff's `+` lines.
+- For **conflicts**: apply the upgrade changes while preserving the project's
+  customizations. Use your judgement to merge. If uncertain, show both versions
+  and ask the user.
+- For **new files**: create them at the mapped path.
+- For **deleted files**: remove them.
+
+**Important considerations:**
+
+- When updating `package.json`, update the `react-native` version and any
+  related dependencies mentioned in the diff (e.g. `react`, `@react-native/*`
+  packages, Gradle versions, CocoaPods versions).
+- Do NOT run `npm install` / `yarn install` / `pod install` automatically.
+  Inform the user these steps are needed after the upgrade.
+- Refer to the [references](#references) section for version-specific guidance
+  on breaking changes and migration notes.
+
+### 7. Update third-party native dependencies
+
+Scan the project's `dependencies` and `devDependencies` in `package.json` for
+third-party React Native libraries that contain **native code** (i.e. they have
+an `ios/` or `android/` directory, or are known native modules). Common examples
+include `react-native-screens`, `react-native-reanimated`,
+`react-native-gesture-handler`, `@react-native-async-storage/async-storage`,
+`react-native-svg`, `react-native-safe-area-context`, etc.
+
+For each candidate dependency:
+
+1. **Fetch the library's README** from its GitHub repository or npm page.
+2. **Look for a React Native version compatibility table or section** — many
+   native libraries document which versions of their package support which React
+   Native versions (e.g. a "Compatibility" or "Version Support" table).
+3. **If the README contains a compatibility table** that maps the target React
+   Native version to a specific library version, include that library version
+   bump in the upgrade plan.
+4. **If the README does not mention version compatibility with React Native
+   versions**, skip the library — do not guess or assume an upgrade is needed.
+
+Present all proposed dependency bumps alongside the diff-based changes in step 5
+(grouped under a **Third-party native dependencies** section). For each:
+
+- State the current version, the proposed version, and link to the compatibility
+  info you found.
+- If multiple major versions are compatible, prefer the latest stable version
+  that supports the target React Native version.
+
+Apply these version bumps to `package.json` as part of step 6.
+
+### 8. Post-upgrade checklist
+
+After applying all changes, present the user with a checklist:
+
+- [ ] Run `npm install` or `yarn install` to update JS dependencies
+- [ ] Run `cd ios && bundle exec pod install` (or `npx pod-install`) to update
+      native iOS dependencies
+- [ ] Run a clean build for Android: `cd android && ./gradlew clean`
+- [ ] Run a clean build for iOS: `cd ios && xcodebuild clean`
+- [ ] Run the app on both platforms to verify it launches
+- [ ] Run the project's test suite
+- [ ] Review any conflict resolutions for correctness
+- [ ] Check the [React Native changelog](https://github.com/facebook/react-native/blob/main/CHANGELOG.md) for additional breaking changes
+- [ ] Check the [Upgrade Helper web UI](https://react-native-community.github.io/upgrade-helper/?from=<currentVersion>&to=<targetVersion>) for any supplementary notes

+# Upgrade Helper API Reference
+
+The [React Native Upgrade Helper](https://react-native-community.github.io/upgrade-helper/)
+uses pre-computed diffs from
+[react-native-community/rn-diff-purge](https://github.com/react-native-community/rn-diff-purge).
+
+## Endpoints
+
+All endpoints are plain HTTP GET requests with no authentication required.
+
+### List available versions
+
+```
+GET https://raw.githubusercontent.com/react-native-community/rn-diff-purge/master/RELEASES
+```
+
+Returns a plain-text file with one version per line.
+
+### Fetch a diff between two versions
+
+```
+GET https://raw.githubusercontent.com/react-native-community/rn-diff-purge/diffs/diffs/{fromVersion}..{toVersion}.diff
+```
+
+Returns a standard unified diff (same format as `git diff` output).
+
+**Example:**
+
+```
+https://raw.githubusercontent.com/react-native-community/rn-diff-purge/diffs/diffs/0.73.0..0.74.0.diff
+```
+
+### View a file at a specific version
+
+```
+GET https://raw.githubusercontent.com/react-native-community/rn-diff-purge/release/{version}/RnDiffApp/{path}
+```
+
+### GitHub compare view
+
+```
+https://github.com/react-native-community/rn-diff-purge/compare/release/{fromVersion}..release/{toVersion}
+```
+
+### Web UI with pre-filled versions
+
+```
+https://react-native-community.github.io/upgrade-helper/?from={fromVersion}&to={toVersion}
+```
+
+## Diff format notes
+
+- All file paths are prefixed with `RnDiffApp/` (the template project name).
+- The default app name is `RnDiffApp` with Android package `com.rndiffapp`.
+- When applying diffs, replace these template names with the actual project's
+  app name and package identifiers.
+- Binary files (e.g. Gradle wrapper JAR) appear as binary patch deltas and
+  should be downloaded directly from the target version's branch instead of
+  applying the diff.
+
