+# Template Migration Tool
+
+This tool migrates Angular templates from using i18n pipes (`{{ 'key' | i18n }}`) to Angular's standard i18n attributes (`<span i18n="@@key">text</span>`).
+
+## Features
+
+- **Analysis**: Analyze current i18n pipe usage in templates
+- **Migration**: Transform i18n pipes to i18n attributes
+- **Validation**: Check for remaining i18n pipe usage after migration
+- **Comparison**: Generate before/after comparison reports
+- **Backup**: Create backup files before migration
+- **Dry-run**: Preview changes without applying them
+
+## Usage
+
+### Prerequisites
+
+Make sure you're in the `scripts/migration/i18n` directory:
+
+```bash
+cd scripts/migration/i18n
+```
+
+### Commands
+
+#### Analyze Templates
+
+Analyze current i18n pipe usage in templates:
+
+```bash
+npm run template-analyze -- --pattern "**/*.html" --verbose
+```
+
+Options:
+
+- `--pattern <pattern>`: Glob pattern for template files (default: `**/*.html`)
+- `--output <path>`: Save analysis report to file
+- `--verbose`: Enable verbose logging
+
+#### Migrate Templates
+
+Migrate templates from i18n pipes to i18n attributes:
+
+```bash
+npm run template-migrate -- --pattern "**/*.html" --dry-run --verbose
+```
+
+Options:
+
+- `--pattern <pattern>`: Glob pattern for template files (default: `**/*.html`)
+- `--file <path>`: Migrate specific file only
+- `--dry-run`: Preview changes without applying them
+- `--output <path>`: Output directory for migration reports
+- `--backup`: Create backup files before migration
+- `--verbose`: Enable verbose logging
+
+#### Validate Migration
+
+Check for remaining i18n pipe usage after migration:
+
+```bash
+npm run template-validate -- --pattern "**/*.html" --verbose
+```
+
+Options:
+
+- `--pattern <pattern>`: Glob pattern for template files (default: `**/*.html`)
+- `--verbose`: Enable verbose logging
+
+#### Compare Templates
+
+Generate before/after comparison for a single template:
+
+```bash
+npm run template-compare -- --file "path/to/template.html"
+```
+
+Options:
+
+- `--file <path>`: Template file to compare (required)
+- `--output <path>`: Save comparison report to file
+- `--verbose`: Enable verbose logging
+
+#### Rollback Migration
+
+Restore files from backup:
+
+```bash
+npm run template-cli -- rollback --backup-dir "./migration-reports/backups"
+```
+
+Options:
+
+- `--backup-dir <path>`: Path to backup directory (default: `./migration-reports/backups`)
+- `--verbose`: Enable verbose logging
+
+## Examples
+
+### Basic Migration Workflow
+
+1. **Analyze current usage**:
+
+   ```bash
+   npm run template-analyze -- --pattern "src/**/*.html" --output analysis-report.md
+   ```
+
+2. **Preview migration (dry-run)**:
+
+   ```bash
+   npm run template-migrate -- --pattern "src/**/*.html" --dry-run --verbose
+   ```
+
+3. **Perform migration with backup**:
+
+   ```bash
+   npm run template-migrate -- --pattern "src/**/*.html" --backup --output ./migration-reports
+   ```
+
+4. **Validate results**:
+   ```bash
+   npm run template-validate -- --pattern "src/**/*.html"
+   ```
+
+### Single File Migration
+
+1. **Compare a single file**:
+
+   ```bash
+   npm run template-compare -- --file "src/app/component.html" --output comparison.md
+   ```
+
+2. **Migrate a single file**:
+   ```bash
+   npm run template-migrate -- --file "src/app/component.html" --backup
+   ```
+
+## Transformation Examples
+
+### Interpolation
+
+**Before:**
+
+```html
+<h1>{{ 'welcome' | i18n }}</h1>
+```
+
+**After:**
+
+```html
+<h1><span i18n="@@welcome">welcome</span></h1>
+```
+
+### Attribute Binding
+
+**Before:**
+
+```html
+<button [title]="'clickMe' | i18n">Click</button>
+```
+
+**After:**
+
+```html
+<button [title]="clickMe" i18n-title="@@click-me">Click</button>
+```
+
+### Complex Templates
+
+**Before:**
+
+```html
+<div>
+  <h1>{{ 'appTitle' | i18n }}</h1>
+  <nav>
+    <a [title]="'homeLink' | i18n" href="/">{{ 'home' | i18n }}</a>
+  </nav>
+</div>
+```
+
+**After:**
+
+```html
+<div>
+  <h1><span i18n="@@app-title">appTitle</span></h1>
+  <nav>
+    <a [title]="homeLink" i18n-title="@@home-link" href="/"><span i18n="@@home">home</span></a>
+  </nav>
+</div>
+```
+
+## Key Transformations
+
+- **Translation keys**: Converted from camelCase/snake_case to kebab-case IDs
+
+  - `camelCaseKey` → `@@camel-case-key`
+  - `snake_case_key` → `@@snake-case-key`
+  - `dotted.key.name` → `@@dotted-key-name`
+
+- **Interpolations**: Wrapped in `<span>` elements with `i18n` attributes
+- **Attribute bindings**: Converted to `i18n-{attribute}` attributes
+- **Parameters**: Currently preserved as-is (may need manual review)
+
+## Output Files
+
+When using `--output` option, the tool generates:
+
+- **Analysis reports**: Markdown files with usage statistics
+- **Migration reports**: Detailed change logs with before/after comparisons
+- **Backup files**: Original files with `.backup` extension
+- **Comparison reports**: Side-by-side before/after views
+
+## Error Handling
+
+The tool includes comprehensive error handling:
+
+- **File not found**: Graceful handling of missing files
+- **Parse errors**: Detailed error messages for malformed templates
+- **Validation failures**: Automatic rollback on transformation errors
+- **Backup creation**: Automatic backup before destructive operations
+
+## Testing
+
+Run the CLI tests:
+
+```bash
+npm test -- templates/cli.spec.ts
+```
+
+The test suite covers:
+
+- Analysis functionality
+- Dry-run migration
+- Actual file migration
+- Validation of results
+- Comparison report generation
+- Error scenarios
+
+## Integration
+
+This tool is part of the larger Angular i18n migration suite. Use it in conjunction with:
+
+- **TypeScript migrator**: For migrating `I18nService.t()` calls to `$localize`
+- **Build system updates**: For configuring Angular's i18n build process
+- **Translation file conversion**: For converting JSON to XLIFF format
+
+## Troubleshooting
+
+### Common Issues
+
+1. **No files found**: Check your pattern and current directory
+2. **Permission errors**: Ensure write permissions for target files
+3. **Parse errors**: Check for malformed HTML in templates
+4. **Validation failures**: Review transformation accuracy
+
+### Debug Mode
+
+Use `--verbose` flag for detailed logging:
+
+```bash
+npm run template-migrate -- --pattern "**/*.html" --verbose --dry-run
+```
+
+This will show:
+
+- Files being processed
+- Transformations being applied
+- Validation results
+- Error details
