+### 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.  
-> Note: the second argument can be empty, "forEach" (default), "forFirst" or "atEnd";
\ No newline at end of file
+* 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!!!
