-## Usage
-We recommend the use of TypeScript for best in class intellisense support.
-
-```typescript
-import { Smartstream } from 'smartstream'
-import * as gUglify from 'gulp-uglify'
-
-let mySmartstream = new Smartstream([
-    gulp.src(['./file1.js','./file2.js']),
-    gUglify(),
-    gulp.dest('./some/output/path')
-])
-
-mySmartstream.onError((err) => { /* handle error */ }) // handles all errors in stream
-myStream.onCustomEvent('myeventname', (args...) => { /* Do something */ }) // emit an custom event anywhere in your stream
-mySmartstream.run().then(() => {/* do something when stream is finished */})
-```

+# @push.rocks/smartstream
+simplifies access to node streams
+
+## Install
+To install `@push.rocks/smartstream`, you can use npm or yarn as follows:
+
+```bash
+npm install @push.rocks/smartstream --save
+# OR
+yarn add @push.rocks/smartstream
+```
+
+This will add `@push.rocks/smartstream` to your project's dependencies.
+
+## Usage
+
+The `@push.rocks/smartstream` module is designed to simplify working with Node.js streams by providing a set of utilities for creating and manipulating streams. This module makes heavy use of TypeScript for improved code quality, readability, and maintenance. ESM syntax is utilized throughout the examples.
+
+### Importing the Module
+
+Start by importing the module into your TypeScript file:
+
+```typescript
+import * as smartstream from '@push.rocks/smartstream';
+```
+
+### Creating Basic Transform Streams
+
+The module provides utilities for creating transform streams. For example, to create a transform stream that modifies chunks of data, you can use the `createTransformFunction` utility:
+
+```typescript
+import { createTransformFunction } from '@push.rocks/smartstream';
+
+const upperCaseTransform = createTransformFunction<string, string>(async (chunk) => {
+  return chunk.toUpperCase();
+});
+
+// Usage with pipe
+readableStream
+  .pipe(upperCaseTransform)
+  .pipe(writableStream);
+```
+
+### Handling Backpressure with SmartDuplex
+
+`SmartDuplex` is a powerful part of the `smartstream` module designed to handle backpressure effectively. Here's an example of how to create a `SmartDuplex` stream that processes data and respects the consumer's pace:
+
+```typescript
+import { SmartDuplex } from '@push.rocks/smartstream';
+
+const processDataDuplex = new SmartDuplex({
+  async writeFunction(chunk, { push }) {
+    const processedChunk = await processChunk(chunk); // Assume this is a defined asynchronous function
+    push(processedChunk);
+  }
+});
+
+sourceStream.pipe(processDataDuplex).pipe(destinationStream);
+```
+
+### Stream Combiners
+
+`Smartstream` facilitates easy combining of multiple streams into a single pipeline, handling errors and cleanup automatically. Here's how you can combine multiple streams:
+
+```typescript
+import { StreamWrapper } from '@push.rocks/smartstream';
+
+const combinedStream = new StreamWrapper([
+  readStream,       // Source stream
+  transformStream1, // Transformation
+  transformStream2, // Another transformation
+  writeStream       // Destination stream
+]);
+
+combinedStream.run()
+  .then(() => console.log('Processing completed.'))
+  .catch(err => console.error('An error occurred:', err));
+```
+
+### Working with StreamIntake
+
+`StreamIntake` allows for more dynamic control of the reading process, facilitating scenarios where data is not continuously available:
+
+```typescript
+import { StreamIntake } from '@push.rocks/smartstream';
+
+const streamIntake = new StreamIntake<string>();
+
+// Dynamically push data into the intake
+streamIntake.pushData('Hello, World!');
+streamIntake.pushData('Another message');
+
+// Signal end when no more data is to be pushed
+streamIntake.signalEnd();
+```
+
+### Real-world Scenario: Processing Large Files
+
+Consider a scenario where you need to process a large CSV file, transform the data row-by-row, and then write the results to a database or another file. With `smartstream`, you could create a pipe that reads the CSV, processes each row, and handles backpressure, ensuring efficient use of resources.
+
+```typescript
+import { SmartDuplex, createTransformFunction } from '@push.rocks/smartstream';
+import fs from 'fs';
+import csvParser from 'csv-parser'; // Assume this is a CSV parsing library
+
+const csvReadTransform = createTransformFunction<any, any>(async (row) => {
+  // Process row
+  return processedRow;
+});
+
+fs.createReadStream('path/to/largeFile.csv')
+  .pipe(csvParser())
+  .pipe(csvReadTransform)
+  .pipe(new SmartDuplex({
+    async writeFunction(chunk, { push }) {
+      await writeToDatabase(chunk); // Assume this writes to a database
+    }
+  }))
+  .on('finish', () => console.log('File processed successfully.'));
+```
+
+This example demonstrates reading a large CSV file, transforming each row with `createTransformFunction`, and using a `SmartDuplex` to manage the processed data flow efficiently, ensuring no data is lost due to backpressure issues.
+
+### Conclusion
+
+`@push.rocks/smartstream` offers a robust set of tools for working with Node.js streams, providing a more intuitive and reliable way to create, manipulate, and combine streams. By leveraging TypeScript and ESM syntax, `smartstream` enables developers to build more maintainable and type-safe stream-based solutions.
