## Chrome OS Devices

Chrome OS credits all the open source projects used in each version of Chrome OS
on each device.

There is no single license file that is correct for all devices and all
versions, so please go to settings/help (or type chrome://help) and click on
"open source software" (or type chrome://credits and chrome://os-credits).

If you would like an online version, an older version of the
OS credits can be found here:
