## What it is
Google's official collection of sample code for Chrome Extensions, organized into single-API samples and full-featured functional samples. It serves as reference material for learning the Chrome extension platform, including Manifest V3 APIs.

## Use cases
- learn how to build a chrome extension
- find example code for chrome extension APIs
- understand manifest v3 service workers and permissions
- see how to inject content scripts into web pages
- build a side panel or popup UI extension
- migrate an extension from manifest v2 to v3

## When to choose
- you are developing a Chrome or Chromium browser extension and want official, working example code
- you want to learn a specific extension API like tabs, bookmarks, cookies, or downloads
- you need a starting template for a full-featured extension

## When to avoid
- you need a production-ready extension framework or build tooling rather than examples
- you target Firefox or Safari extensions without Chrome-specific APIs
- you are looking for deprecated Chrome Apps platform support
