+    """
+    Decorate an iterable object, returning an iterator which acts exactly
+    like the orignal iterable, but prints a dynamically updating
+    progressbar.
     
     Parameters
     ----------
-    iterable: iterable
-        Iterable to show progress for.
-    desc: str, optional
-        A short string, describing the progress, that is added in the beginning
-        of the line.
+    iterable  : iterable
+        Iterable to decorate with a progressbar.
+    desc  : str, optional
+        Prefix for the progressbar.
     total  : int, optional
-        The number of expected iterations. If not given, len(iterable) is used
-        if it is defined.
+        The number of expected iterations. If not given, len(iterable) is
+        used if possible. As a last resort, only basic progress statistics
+        are displayed.
     file  : `io.TextIOWrapper` or `io.StringIO`, optional
-        A file-like object to output the progress message to. By default,
-        sys.stderr is used.
+        Specifies where to output the progress messages.
     leave  : bool, optional
-        If it is False (default), tqdm deletes its traces from screen after
-        it has finished iterating over all elements.
+        if unset, removes all traces of the progressbar upon termination of
+        iteration [default: False].
+    ncols  : int, optional
+        The width of the entire output message. If sepcified, dynamically
+        resizes the progress meter [default: None]. The fallback meter
+        width is 10.
     mininterval  : float, optional
-        If less than mininterval seconds have passed since the last progress
-        meter update, it is not updated again (default: 0.5).
-    miniters : float, optional
-        If less than miniters iterations have passed since the last progress
-        meter update, it is not updated again (default: 1).
+        Minimum progress update interval, in seconds [default: 0.5].
+    miniters  : int, optional
+        Minimum progress update interval, in iterations [default: 1].
     
+    Returns
+    -------
+    out  : decorated iterator.
