+### Special commands
+Use macOS darkmode window style:
+```python
+import customtkinter
+
+customtkinter.enable_macos_darkmode()  # get darkmode window style
+customtkinter.disable_macos_darkmode()  # disable darkmode (important!)
+```
+
+If you dont use ``root_tk.mainloop()``, then you have to deactivate
+the threaded search for a change of the system appearance mode, and
+do it yourself in your main loop where you call ``root_tk.update()``.
+```python
+customtkinter.deactivate_threading()  # call this at the beginning
+customtkinter.update_appearance_mode()  # then call this in the loop
+```
