-
-The backend repository is hosted @ https://github.com/hacs/integration
-
-## Target branch for contributor PRs
-
-When contributing to the backend, target your PR against the `main` branch.
-
-
-## Creating your code changes using the devcontainer
-
-1. Spin up the [devcontainer](/docs/contribute/devcontainer.md).
-
-2. Add your code changes.
-3. To start a preview of the application, issue the following command:
-
-    ```bash
-    scripts/develop
-    ```
-
-    - You have now started a local instance of Home Assistant with HACS on `http://localhost:8123`
-
-
-    - To use and see HACS inside the local Home Assistant instance, you need to [configure it in the Home Assistant UI](/docs/use/configuration/basic.md)
-
-4. When you are happy with the result, push the changes to your fork and create a PR to have it merged to the HACS base.
+To work on the Marketplace, see the [Home Assistant contributor documentation](https://contributors.home-assistant.io/). The integration lives in [home-assistant/core](https://github.com/home-assistant/core), as `homeassistant/components/marketplace`.

+title: HACS and the Marketplace
+description: "Starting with Home Assistant 2026.11, HACS is built into Home Assistant as the Marketplace. What that means for you."
+---
+
+Starting with Home Assistant 2026.11, HACS ships with Home Assistant itself, as the **Marketplace** integration. You find it under **Settings** > **Marketplace**. There is nothing to download anymore.
+
+The Marketplace is HACS, brought into Home Assistant: the same catalog, the same repositories, and the same `hacs.json`. Development continues in Home Assistant, so HACS itself, the custom integration, doesn't get new features anymore.
+
+## What this means for you
+
+| You | Where to go |
+| --- | --- |
+| Use HACS on Home Assistant 2026.10 or older | Keep using HACS. The [user documentation](/docs/use/index.md) on this site still applies. Before you upgrade, read [Upgrading to Home Assistant 2026.11](#upgrading-to-home-assistant-202611). |
+| Use Home Assistant 2026.11 or newer | The [Marketplace documentation](https://next.home-assistant.io/integrations/marketplace/). |
+| Publish a repository | The [Marketplace publishing documentation](https://contributors.home-assistant.io/marketplace/). Getting into the catalog still works the same, through [hacs/default](https://github.com/hacs/default). |
+| Want to contribute code | The [Home Assistant contributor documentation](https://contributors.home-assistant.io/). |
+
+## Upgrading to Home Assistant 2026.11
+
+You don't need to do anything. When Home Assistant starts after the update, the Marketplace takes over from HACS:
+
+- Everything you downloaded with HACS stays installed, and keeps getting updates.
+- Your custom repositories and update entities carry over, with their names, areas, and labels. The update entities keep their entity IDs, so automations and dashboards that use them keep working.
+- HACS itself is removed. Bookmarks to `/hacs` open the Marketplace.
+
+A few things work differently:
+
+- The Marketplace is under **Settings**, not in the sidebar. The HACS options, like the sidebar title and icon, are gone.
+- AppDaemon apps and Python scripts are no longer managed. Their files stay where they are and keep working, but they don't get updates anymore. A repair tells you which ones this concerns.
+- Dashboard resources are served from `/local/community/` now. The old `/hacsfiles/` paths keep working. If you configured resources in YAML, a repair reminds you to change them.
+- HACS can't be installed on Home Assistant 2026.11 or newer. Home Assistant blocks the custom integration, because the Marketplace replaces it.
+
+The [Coming from HACS](https://next.home-assistant.io/integrations/marketplace/#coming-from-hacs) section of the Marketplace documentation has all the details, including what changes for templates and custom tools that use HACS.
+
+## What stays here
+
+- **The catalog.** The list of repositories everyone sees is still [hacs/default](https://github.com/hacs/default), and the Marketplace reads the same data HACS does. Submitting a repository works as before.
+- **The checks.** The [HACS action](/docs/publish/action.md) and the [checks for the catalog](/docs/publish/include.md) are documented in the publishing section of this site.
+- **HACS before 2026.11.** The user documentation and the FAQ on this site describe HACS, for everyone who hasn't upgraded yet.
+
+## Feature requests and bugs
+
+- **Feature requests and ideas:** the [Marketplace category](https://github.com/orgs/home-assistant/discussions/categories/marketplace) of the Home Assistant discussions.
+- **Bugs in the Marketplace:** the [open Marketplace issues](https://github.com/home-assistant/core/issues?q=sort%3Aupdated-desc+is%3Aissue+state%3Aopen+label%3A%22integration%3A+marketplace%22) in the Home Assistant core repository. Open a new one there if yours isn't reported yet.
+- **Bugs in something you downloaded:** the repository of that integration, card, or theme.
