# Chrome Extensions samples

Official samples for Chrome Extensions and the Chrome Apps platform.
Note that Chrome Apps are deprecated—learn more [on the Chromium blog](https://blog.chromium.org/2020/08/changes-to-chrome-app-support-timeline.html).

For more information on extensions, see [Chrome Developers](https://developer.chrome.com).

## Samples

The directory structure is as follows:

* api/ - extensions focused on a single API package
* howto/ - extensions that show how to perform a particular task
* tutorials/ - multi-step walkthroughs referenced inline in the docs
* extensions/ - full featured extensions spanning multiple API packages
* apps/ - deprecated Chrome Apps platform (not listed below)

To experiment with these samples, please clone this repo and use 'Load Unpacked Extension'.
