 ### Asynchronous filename generation
 
-The `tmpName()` function accepts the `prefix`, `postfix`, `dir`, etc. parameters also:
+Using `tmpName()` you can create temporary file names asynchronously.
+The function accepts all standard options, e.g. `prefix`, `postfix`, `dir`, and so on.

+You can also leave out the options altogether and just call the function with a callback as first parameter.

 The `tmpNameSync()` function works similarly to `tmpName()`.
