-### Usage
-```javascript
-var gulp = require("gulp");
-var gulpFunction = require("gulp-function");
-var Q = require("q");
+For further information read the linked docs at the top of this README.
 
-var myFunction = function () {
-    var done = Q.defer();
-    console.log("Hello World!")
-    
-    // NOTE:
-    // you can use done.resolve as callback function
-    // of any async tasks within this function
-    done.resolve();
-    
-    return done.promise;

-gulp.task('gulpTest',function() {
-    var stream = gulp.src('./mydir/*.something')
-        .pipe(gulpFunction(myFunction,'forEach')) //read the notes below
-        .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.  
-* 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.
-    *  "atEnd" - executes like "forFirst" but with every chunk/vinylfile in the stream;
-    *  "atLast" - executes after all chunks have passed and are processed in full.
-       That means the stream's "finish" event fires before "atLast" is executed!!!

+* 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.

+    *  "atEnd" - executes after all chunks have passed and are processed in full.
