+
+## Usage
+
+Please use TypeScript for best in class intellisense.
+
+```typescript
+import gulp = require('gulp');
+import gulpFunction from 'gulp-function'; // default ES6 export
+// import {forFirst, forEach, atEnd} from 'gulp-function'
+
+let myAsyncFunction = async (file, enc) => {
+  // await some async stuff
+};
+
+gulp.task('gulpTest', function() {
+  let stream = gulp
+    .src('./mydir/*.something')
+    .pipe(gulpFunction(myAsyncFunction, 'forEach')) //read the notes below
+    // .pipe(forEach(myAsyncFunction)) // if imported as >> import { forEach } from 'gulp-function' <<
+    .pipe(gulp.dest('./build/'));
+  return stream; // by returning the stream gulp knows when our task has finished.
+});
+```
+
+### Notes
+
+- The first argument of gulpFunction can also be an **array of multiple functionnames**.
+  Each function can return a promise. The pipe stop will finish when every promise is fullfilled.
+  When providing an array of functions be careful with modifying the file object -> race condition
+- The second argument can be empty, it defaults to "forEach"
+- The following options are available:
+  - "forFirst" - executes when first chunk/vinylfile of the stream reaches the pipestop.
+    file is pushed further down the line when function's returned promise is fullfilled.
+  - "forEach" - executes like "forFirst" but with every chunk/vinylfile in the stream;
+  - "atEnd" - executes after all chunks have passed and are processed in full.
+    That means the stream's "finish" event fires **before "atLast" is executed**!!!
+
