Hi, thank you very much, but how I use this? the zip contains icns file types and no readme file :(

it is a custom keyboard layout. You put the .bundle file in library/keyboard layouts, logout login, and then go to system preferences / keyboard / input sources and add the new keyboard.

Yes, see this page.
