+How to use a layout this with the pico-ducky repository.
+
+#### Go to the [latest release page](https://github.com/Neradoc/Circuitpython_Keyboard_Layouts/releases/latest), look if your language is in the list.
+
+## If your language/layout is in the bundle
+
+Download the `py` zip, named `circuitpython-keyboard-layouts-py-XXXXXXXX.zip`
+
+*You can use the mpy version targetting the version of Circuitpython that is on the device, but on Raspberry Pi Pico you don't need it - they only reduce file size and memory use on load, which the pico has plenty of.*
+
+## If your language/layout is not in the bundle
+
+Try the online generator, it should get you a zip file with the bundles for yout language
+
+https://www.neradoc.me/layouts/
+
+## Now you have a zip file
+
+#### Find your language/layout in the lib directory 
+
+For a language `LANG`, copy the following files from the zip's `lib` folder to the `lib` folder of the board. Don't change the names of the files.
+
+- `keyboard_layout.py`
+- `keyboard_layout_win_LANG.py`
+- `keycode_win_LANG.py`
+
+#### Modify the pico-ducky code to use your language file:
+
+At the start of the file replace:
+
+```py
+from adafruit_hid.keyboard_layout_us import KeyboardLayoutUS
+from adafruit_hid.keycode import Keycode
+```
+
+With this. Change `LANG` for you language, so the module names match the files without the extention.
+```py
+from keyboard_layout_win_LANG import KeyboardLayout
+from keycode_win_LANG import Keycode
+```
+
+And also replace:
+```py
+layout = KeyboardLayoutUS(kbd)
+```
+With:
+```py
+layout = KeyboardLayout(kbd)
+```
