+## Usage
+
+Use TypeScript for best in class instellisense.
+
+```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 */})
+```
+
+## Contribution
+
+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). :)
