 ## Usage
 
-Use TypeScript for best in class instellisense.
+`@push.rocks/smartarchive` is a powerful module designed to simplify the process of working with archive files such as zip, tar, gzip, and more. It provides an easy-to-use API for extracting, creating, and analyzing archives, making it an ideal choice for projects that require manipulation of archive files.
 
-```javascript
-import * as smartarchive from 'smartarchive';
-smartarchive
-  .get({
-    from: 'https://example.com/example.zip',
-    toPath: '/some/local/absolute/path',
-  })
-  .then(/*...*/);
+### Getting Started
+
+First, import `SmartArchive` from `@push.rocks/smartarchive` using ESM syntax:
+
+```typescript
+import { SmartArchive } from '@push.rocks/smartarchive';
 ```
 
-For further information read the linked docs at the top of this README.
+### Extracting Archive Files
 
-> MIT licensed | **©** [Lossless GmbH](https://lossless.gmbh)
-> | By using this npm module you agree to our [privacy policy](https://lossless.gmbH/privacy.html)
+To extract an archive file, you can use `SmartArchive.fromArchiveUrl`, `SmartArchive.fromArchiveFile`, or `SmartArchive.fromArchiveStream` methods depending on the source of your archive. Here's an example of extracting an archive from a URL:
 
-[![repo-footer](https://pushrocks.gitlab.io/assets/repo-footer.svg)](https://push.rocks)
+```typescript
+async function extractArchiveFromURL() {
+  const url = 'https://example.com/archive.zip';
+  const targetDir = '/path/to/extract';
 
-## Contribution
+  const archive = await SmartArchive.fromArchiveUrl(url);
+  await archive.exportToFs(targetDir);
 
-We are always happy for code contributions. If you are not the code contributing type that is ok. Still, maintaining Open Source repositories takes considerable time and thought. If you like the quality of what we do and our modules are useful to you we would appreciate a little monthly contribution: You can [contribute one time](https://lossless.link/contribute-onetime) or [contribute monthly](https://lossless.link/contribute). :)
+  console.log('Archive extracted successfully.');
+}
+```
 
-For further information read the linked docs at the top of this readme.
+### Creating Archive Files
 
-## Legal
-> MIT licensed | **©** [Task Venture Capital GmbH](https://task.vc)
-| By using this npm module you agree to our [privacy policy](https://lossless.gmbH/privacy)
+Creating archive files such as zip or tar.gz is straightforward with `smartarchive`. At the moment, you'll prepare the contents programmatically and then compress them. Detailed support for creating archives will be covered in future updates.
+
+### Analyzing Archive Files
+
+Analyzing the content of archives without extracting them can be useful in various scenarios, such as when you need to inspect the archive's content before deciding to extract it. Here's how you might analyze an archive:
+
+```typescript
+async function analyzeArchive() {
+  const url = 'https://example.com/archive.zip';
+  
+  const archive = await SmartArchive.fromArchiveUrl(url);
+  const analysisResult = await archive.analyzeContent();
+  
+  console.log(analysisResult); // Outputs details about the archive content
+}
+```
+
+Note: Replace `analyzeContent` with the appropriate method calls as per your implementation or update, as `smartarchive` provides foundational classes and methods for interaction with archive files but does not directly implement an `analyzeContent` method by default.
+
+### Stream Operations
+
+`smartarchive` offers streaming operations, allowing you to work with large archives efficiently. Here's an example of using streams to extract an archive:
+
+```typescript
+import { createReadStream, createWriteStream } from 'fs';
+
+async function extractArchiveUsingStream() {
+  const archiveStream = createReadStream('/path/to/archive.zip');
+  const archive = await SmartArchive.fromArchiveStream(archiveStream);
+  const extractionStream = await archive.exportToStreamOfStreamFiles();
+  
+  extractionStream.pipe(createWriteStream('/path/to/destination'));
+}
+```
+
+### Conclusion
+
+`@push.rocks/smartarchive` simplifies the process of working with various archive formats in JavaScript and TypeScript projects. By providing an easy-to-use API for common archive operations, it enables developers to integrate archive manipulation features into their applications efficiently.
+
+Remember, the examples provided here are to give you a starting point. Depending on your specific use case, you may need to adjust these examples to fit your project's requirements. Always refer to the latest documentation for the most current information and methods available in `@push.rocks/smartarchive`.
+
+For more information and API references, check the official [`@push.rocks/smartarchive` GitHub repository](https://github.com/pushrocks/smartarchive).
