-## Publishing and Using as a Private NPM Package
-
-Soulcraft Brainy is configured as a private NPM package with restricted access. This section provides information on how to publish and use it within your organization.
-
-### Versioning
-
-This project uses semantic versioning (SemVer):
-
-- **Major version** (`x.0.0`): Breaking changes that may require updates to dependent code
-- **Minor version** (`0.x.0`): New features that don't break existing functionality
-- **Patch version** (`0.0.x`): Bug fixes and other minor changes
-
-The package includes scripts for manual version bumping:
-
-```bash
-# Increment patch version (0.0.x)
-npm run version:patch
-
-# Increment minor version (0.x.0)
-npm run version:minor
-
-# Increment major version (x.0.0)
-npm run version:major
-```
-
-These commands will update the version in package.json and create a git tag for the new version.
-
-### Publishing the Package
-
-To publish updates to the package:
-
-1. Ensure you have the appropriate npm credentials and access to the @soulcraft organization
-2. Update the version using one of the version scripts:
-   ```bash
-   npm run version:patch  # For bug fixes and minor changes
-   npm run version:minor  # For new features
-   npm run version:major  # For breaking changes
-   ```
-3. Use the deploy script to build and publish the package:
-   ```bash
-   npm run deploy
-   ```
-
-Alternatively, you can run the steps separately:
-1. Build the package:
-   ```bash
-   npm run build
-   ```
-2. Publish the package:
-   ```bash
-   npm publish
-   ```
-
-Note that the package has the following configuration in package.json:
-```json
-"private": false,
-"publishConfig": {
-  "access": "restricted"
-}
-```
-
-This ensures that the package is only accessible to users with appropriate permissions within the @soulcraft organization. The `"access": "restricted"` setting limits access to the package to members of the @soulcraft organization, while `"private": false` allows the package to be published to npm.
-
-### Installing the Private Package
-
-To install the package in another project:
-
-1. Ensure you have access to the @soulcraft organization on npm
-2. Add the package to your project:
-   ```bash
-   npm install @soulcraft/brainy
-   ```
-
-3. If you're using a private npm registry, you may need to configure npm to use your organization's registry:
-   ```bash
-   npm config set @soulcraft:registry https://your-private-registry.com/
-   ```

+##### FirestoreSync Conduit Augmentation
+
+Brainy includes a FirestoreSync conduit augmentation that allows for syncing data to Firestore either one-way or
+two-way:
+
+- **One-way sync**: Data is only pushed from Brainy to Firestore
+- **Two-way sync**: Data is synchronized between Brainy and Firestore in both directions
+
+**Prerequisites:**
+
+1. Install Firebase: `npm install firebase`
+2. Set up a Firebase project and enable Firestore
+3. Get your Firebase configuration from the Firebase console
+
+**Usage:**
+
+```typescript
+import { 
+  registerAugmentation,
+  initializeAugmentationPipeline,
+  createFirestoreSyncAugmentation,
+  FirestoreSyncConfig
+} from '@soulcraft/brainy';
+
+// Your Firebase configuration
+const firebaseConfig = {
+  apiKey: "your-api-key",
+  authDomain: "your-project-id.firebaseapp.com",
+  projectId: "your-project-id",
+  storageBucket: "your-project-id.appspot.com",
+  messagingSenderId: "your-messaging-sender-id",
+  appId: "your-app-id"
+};
+
+// Create the FirestoreSync augmentation with one-way sync configuration
+const oneWaySyncConfig: FirestoreSyncConfig = {
+  firebaseConfig,
+  nodesCollection: 'brainy_nodes',
+  edgesCollection: 'brainy_edges',
+  metadataCollection: 'brainy_metadata',
+  syncMode: 'one-way'
+};
+
+// Create and register the augmentation
+const firestoreSync = createFirestoreSyncAugmentation(
+  'brainy-firestore-sync',
+  oneWaySyncConfig
+);
+
+registerAugmentation(firestoreSync);
+
+// Initialize the augmentation pipeline
+initializeAugmentationPipeline();
+
+// Initialize the augmentation
+await firestoreSync.initialize();
+
+// Now you can use the augmentation to sync data
+// For example, to sync a node to Firestore:
+await firestoreSync.syncNodeToFirestore(node);
+
+// Or to sync an edge to Firestore:
+await firestoreSync.syncEdgeToFirestore(edge);
+
+// Or to sync metadata to Firestore:
+await firestoreSync.syncMetadataToFirestore('metadata-id', { key: 'value' });
+
+// You can also use the standard conduit methods:
+// Read data from Firestore
+const response = await firestoreSync.readData({
+  collection: 'brainy_nodes',
+  id: 'node-id'
+});
+
+// Write data to Firestore
+await firestoreSync.writeData({
+  collection: 'custom_collection',
+  id: 'custom-doc-1',
+  document: {
+    name: 'Custom Document',
+    timestamp: new Date()
+  }
+});
+
+// Monitor changes in Firestore
+await firestoreSync.monitorStream('brainy_nodes', (data) => {
+  console.log('Node change detected:', data);
+});
+
+// When done, shut down the augmentation
+await firestoreSync.shutDown();
+```
+
+**Two-way Sync Configuration:**
+
+For two-way synchronization between Brainy and Firestore:
+
+```typescript
+const twoWaySyncConfig: FirestoreSyncConfig = {
+    firebaseConfig,
+    nodesCollection: 'brainy_nodes',
+    edgesCollection: 'brainy_edges',
+    metadataCollection: 'brainy_metadata',
+    syncMode: 'two-way',
+    syncInterval: 30000  // Sync every 30 seconds
+};
+
+const twoWaySync = createFirestoreSyncAugmentation(
+    'brainy-firestore-two-way-sync',
+    twoWaySyncConfig
+);
+```
+
+For more detailed examples, see the [firestoreSyncExample.js](examples/firestoreSyncExample.js) file.
