Learn about developing extensions for Chrome.

> [!WARNING]
> **Warning:** The Chrome Web Store no longer accepts Manifest V2 extensions. Follow the [Manifest V3 Migration guide](https://developer.chrome.com/docs/extensions/migrating) to convert your extension to Manifest V3.

These pages contain guides and reference information for developers who want to
create extensions for the Chrome browser. If you're not sure where to begin,
have a look at the following starting pages:

- [What are extensions?](https://developer.chrome.com/docs/extensions/mv2/overview) to help you understand just what an extension is.
- The [Getting started tutorial](https://developer.chrome.com/docs/extensions/mv2/getstarted) if you're ready for hello, world.

Beyond that, you might find useful entry points in these pages:

- Learn the scope of things in the [Extension development overview](https://developer.chrome.com/docs/extensions/mv2/devguide)
- Pick something from the [samples page](https://github.com/GoogleChrome/chrome-extensions-samples/tree/main/_archive/mv2), install it, and start hacking on it.
- Look for answers in the [Extensions FAQ page](https://developer.chrome.com/docs/extensions/mv2/faq)

In addition to the documentation here, many developers find helpful community content at:

- The [Chrome Extensions Mailing List](https://groups.google.com/a/chromium.org/g/chromium-extensions).
- The Stack Overflow [google-chrome extension](https://stackoverflow.com/tags/google-chrome-extension/info) tag.
