+#### Streaming Files
+
+SmartBucket allows you to work with file streams, which can be useful for handling large files. 
+
+To read a file as a stream:
+
+```typescript
+import { ReplaySubject } from '@push.rocks/smartrx';
+
+async function readFileStream(bucketName: string, filePath: string) {
+  const myBucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
+  if (myBucket) {
+    const fileStream: ReplaySubject<Buffer> = await myBucket.fastGetStream({ path: filePath });
+    fileStream.subscribe({
+      next(chunk: Buffer) {
+        console.log("Chunk received:", chunk.toString());
+      },
+      complete() {
+        console.log("File read completed.");
+      },
+      error(err) {
+        console.error("Error reading file stream:", err);
+      }
+    });
+  } else {
+    console.error(`Bucket ${bucketName} does not exist.`);
+  }
+}
+
+// Use the function
+readFileStream("exampleBucket", "path/to/object.txt");
+```
+
+To write a file as a stream:
+
+```typescript
+import { Readable } from 'stream';
+
+async function writeFileStream(bucketName: string, filePath: string, readableStream: Readable) {
+  const myBucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
+  if (myBucket) {
+    await myBucket.fastPutStream({ path: filePath, dataStream: readableStream });
+    console.log(`File streamed to ${bucketName} at ${filePath}`);
+  } else {
+    console.error(`Bucket ${bucketName} does not exist.`);
+  }
+}
+
+// Create a readable stream from a string
+const readable = new Readable();
+readable.push('Hello world streamed as a file!');
+readable.push(null); // Indicates end of the stream
+
+// Use the function
+writeFileStream("exampleBucket", "path/to/streamedObject.txt", readable);
+```
+
 ### Working with Directories
 
 `@push.rocks/smartbucket` abstracts directories within buckets for easier object management. You can create, list, and delete directories using the `Directory` class.
 
-### Additional Features
+Here's how to list the contents of a directory:
 
-- **Bucket Policies:** Manage bucket policies to control access permissions.
+```typescript
-- **Object Metadata:** Retrieve and modify object metadata.
+async function listDirectoryContents(bucketName: string, directoryPath: string) {
-- **Cloud-Agnostic:** Designed to work with multiple cloud providers, allowing for easier migration or multi-cloud strategies.
+  const myBucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
+  if (myBucket) {
+    const baseDirectory: Directory = await myBucket.getBaseDirectory();
+    const targetDirectory: Directory = await baseDirectory.getSubDirectoryByName(directoryPath);
+    
+    console.log('Listing directories:');
+    const directories = await targetDirectory.listDirectories();
+    directories.forEach(dir => {
+      console.log(`- ${dir.name}`);
+    });
+
+    console.log('Listing files:');
+    const files = await targetDirectory.listFiles();
+    files.forEach(file => {
+      console.log(`- ${file.name}`);
+    });
+  } else {
+    console.error(`Bucket ${bucketName} does not exist.`);
+  }
+}
+
+// Use the function
+listDirectoryContents("exampleBucket", "some/directory/path");
+```
+
+To create a file within a directory:
+
+```typescript
+async function createFileInDirectory(bucketName: string, directoryPath: string, fileName: string, fileContent: string) {
+  const myBucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
+  if (myBucket) {
+    const baseDirectory: Directory = await myBucket.getBaseDirectory();
+    const targetDirectory: Directory = await baseDirectory.getSubDirectoryByName(directoryPath);
+    await targetDirectory.createEmptyFile(fileName); // Create an empty file
+    const file = new File({ directoryRefArg: targetDirectory, fileName });
+    await file.updateWithContents({ contents: fileContent });
+    console.log(`File created: ${fileName}`);
+  } else {
+    console.error(`Bucket ${bucketName} does not exist.`);
+  }
+}
+
+// Use the function
+createFileInDirectory("exampleBucket", "some/directory", "newfile.txt", "Hello, world!");
+```
+
+### Advanced Features
+
+#### Bucket Policies
+
+Manage bucket policies to control access permissions. This feature is dependent on the policies provided by the storage service (e.g., AWS S3, MinIO).
+
+#### Object Metadata
+
+You can retrieve and modify object metadata. Metadata can be useful for storing additional information about an object.
+
+To retrieve metadata:
+
+```typescript
+async function getObjectMetadata(bucketName: string, filePath: string) {
+  const myBucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
+  if (myBucket) {
+    const metadata = await mySmartBucket.minioClient.statObject(bucketName, filePath);
+    console.log("Object metadata:", metadata);
+  } else {
+    console.error(`Bucket ${bucketName} does not exist.`);
+  }
+}
+
+// Use the function
+getObjectMetadata("exampleBucket", "path/to/object.txt");
+```
+
+To update metadata:
+
+```typescript
+async function updateObjectMetadata(bucketName: string, filePath: string, newMetadata: { [key: string]: string }) {
+  const myBucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
+  if (myBucket) {
+    await myBucket.copyObject({
+      objectKey: filePath,
+      nativeMetadata: newMetadata,
+      deleteExistingNativeMetadata: false,
+    });
+    console.log(`Metadata updated for ${filePath}`);
+  } else {
+    console.error(`Bucket ${bucketName} does not exist.`);
+  }
+}
+
+// Use the function
+updateObjectMetadata("exampleBucket", "path/to/object.txt", {
+  customKey: "customValue"
+});
+```
+
+#### Cloud Agnostic
+
+`@push.rocks/smartbucket` is designed to work with multiple cloud providers, allowing for easier migration or multi-cloud strategies. This means you can switch from one provider to another with minimal changes to your codebase.
 
 Remember, each cloud provider has specific features and limitations. `@push.rocks/smartbucket` aims to abstract common functionalities, but always refer to the specific cloud provider's documentation for advanced features or limitations.
 
-> **Note:** This document focuses on basic operations to get you started with `@push.rocks/smartbucket`. For advanced usage, including streaming data, managing bucket policies, and handling large file uploads, refer to the detailed API documentation and examples.
+This guide covers the basic to advanced scenarios of using `@push.rocks/smartbucket`. For further details, refer to the API documentation and examples.
