 Press `h` to show the hotkeys:
 - `Space` sweeps through clock-displays
-- `c` toggles the colors
+- `c` and `shift-c` sweeps through the color-schemes
 - `+` increases size
 - `-` decreases size
 - `0` resets size
+- `s` shows settings
 
-I wanted to have a fullscreen clock for my dual-screen setup for a longer time. After I have learned the very basics of HTML and Javascript, I decided to write my own little fullscreen-clock. Afterwards I decided to make it available for others, so I added a help-function (press `h`) and after some refactoring I put it on GitHub.

 There are at least a dozen more features in my head I could implement but this is what I have so far. And I don't know if this will work on your computer (regarding the browser, your keyboard-language etc).
+
+I will try to keep this tiny application updated and I hopefully I fill continue to add more features.
