 ## What's Reskinner?
+
 Reskinner is a Python 3 plugin for PySimpleGUI's Tkinter port which enables changing the theme of a PySimpleGUI window on the fly without the need for re-instantiating the window.
 
 Please consider starring the project if you find it useful.
 
 ## Example Usage (Demo)
 
 ```python
-# Reskinner Version 2
-
-from psg_reskinner import reskin, animated_reskin, __version__
-from PySimpleGUI import Window, Text, Button, Push, Titlebar, theme_list, theme, LOOK_AND_FEEL_TABLE, TIMEOUT_KEY
+# Reskinner Version 2.3.13
+from psg_reskinner import animated_reskin, __version__
+from PySimpleGUI import Window, Text, Button, Push, Titlebar, theme, theme_list, LOOK_AND_FEEL_TABLE
 from random import choice as rc
 
-rmenu = ['', ['Hi', 'There']]
+right_click_menu = ['', [['Hi', ['Next Level', ['Deeper Level', ['a', 'b', 'c']], 'Hoho']], 'There']]
 
 window_layout = [
     [Titlebar('Reskinner Demo')],
     [Text('Hello!', font=('Helvetica', 20))],
     [Text('You are currently running Reskinner instead of importing it.')],
-    [Text('The theme of this window changes every 3 seconds.')],
+    [Text('The theme of this window changes every 2 seconds.')],
     [Text('Changing to:')],
-    [Button('DarkBlue3', k='ctheme', font=('Helvetica', 16), right_click_menu=rmenu)],
+    [Button('DarkBlue3', k='current_theme', font=('Helvetica', 16), right_click_menu=right_click_menu)],
     [Text(f'Reskinner v{__version__}', font=('Helvetica', 8), pad=(0, 0)), Push()],
 ]
 
-window = Window('Reskinner Demo', window_layout, element_justification='center')
+window = Window('Reskinner Demo', window_layout, element_justification='center', keep_on_top=True)
+
+def _reskin_job():
+    themes = theme_list()
+    themes.remove(theme())
+    new = rc(themes)
+    window['current_theme'].update(new)
+    animated_reskin(
+        window=window,
+        new_theme=new,
+        theme_function=theme,
+        lf_table=LOOK_AND_FEEL_TABLE,
+    )
+    window.TKroot.after(2000, _reskin_job)
+
+started = False
 
 while True:
 
-    e, v = window.Read(timeout=2000)
+    e, v = window.read(timeout=2000)
 
     if e in (None, 'Exit'):
         window.Close()
         break
 
-    elif e == TIMEOUT_KEY:
-        new = rc(theme_list())
-        window['ctheme'].update(new)
-        animated_reskin(window=window,
-                        new_theme=new,
-                        theme_function=theme,
-                        lf_table=LOOK_AND_FEEL_TABLE,)
-``` 
+    if not started:
+        _reskin_job()
+        started = True
+
+```
