Simply include in page, along with dependencies, and give your checkboxes data-checkyo data attributes
<label><input type="checkbox" data-checkyo>Click me, yo!</label>
As the example above shows, you also need to embed the checkbox input inside the associated label tag, which has the desirable side-effect of making labels clickable.
The example below shows how to use it with radio buttons
<label><input type="radio" name="test" data-checkyo>Moja</label> <label><input type="radio" name="test" data-checkyo>Mbili</label> <label><input type="radio" name="test" data-checkyo>Tatu</label>
