+# Remove Default Exports in TypeScript
+
+This codemod demonstrates how to automatically convert default exports to named exports in your TypeScript codebase. The migration script makes this process simple by handling all the tedious manual updates automatically.
+
+## How the Migration Script Works
+
+The script automates the entire migration process in a few key steps:
+
+1. **File Detection and Analysis**
+   ```python
+   codebase = Codebase("./")
+   for file in codebase.files:
+       if "/shared/" not in file.filepath:
+           continue
+   ```
+   - Automatically identifies shared TypeScript files
+   - Analyzes export structures
+   - Determines necessary export modifications
+
+2. **Export Conversion**
+   ```python
+   for export in file.exports:
+       if export.is_default_export():
+           export.make_non_default()
+   ```
+   - Converts default exports to named exports
+   - Ensures corresponding non-shared files are updated
+   - Preserves existing export configurations
+
+## Common Migration Patterns
+
+### Default Export Conversion
+```typescript
+// Before
+export default function myFunction() {}
+
+// After
+export function myFunction() {}
+```
+
+### Re-export Conversion
+```typescript
+// Before
+export { default } from './module';
+
+// After
+export { myFunction } from './module';
+```
+
+## Running the Migration
+
+```bash
+# Install Codegen
+pip install codegen
+# Run the migration
+python run.py
+```
