+Install the plugin in your project, alongside the Emigrate CLI:
+
+```bash
+npm install --save-dev @emigrate/cli @emigrate/plugin-storage-fs
+```
+
+## Usage
+
+Configure the plugin in your `emigrate.config.js` file:
+
+```js
+import storageFs from '@emigrate/plugin-storage-fs';
+
+export default {
+  directory: 'migrations',
+  plugins: [storageFs({ filename: '.migrated.json' })],
+};
+```
