On first launch, onboarding creates the administrator, connects optional services, and builds the first board. A
|
|
compatible SQLite backup can also be restored from the welcome screen.
|
|
|
|
If onboarding returns after a restart, check that `/appdata` is writable and persisted. See the
|
|
[Docker installation guide](/docs/getting-started/installation/docker).

## Core concepts
|
|
|
|
### Boards
|
|
|
|
A **board** is a dashboard page containing apps, widgets, and Containers. Boards can be public or restricted to users
|
|
and groups. Each user can choose a home board.
|
|
|
|

|
|
|
|
See [Boards](/docs/management/boards) for responsive layouts, access control, appearance, and home-board settings.
|
|
|
|
### Apps
|
|
|
|
An **app** is a saved shortcut: a name, URL, icon, and optional status check. Add an App tile or a Bookmarks widget to
|
|
show apps on a board.
|
|
|
|

|
|
|
|
See [Apps](/docs/management/apps) or [Icons](/docs/advanced/icons).
|
|
|
|
### Integrations
|
|
|
|
An **integration** is a server-side connection from Homarr to a supported service such as Sonarr, Home Assistant, or
|
|
Docker. Integrations provide data and actions to widgets. They can also be linked to apps.
|
|
|
|

|
|
|
|
See [Managing integrations](/docs/management/integrations) and the
|
|
[integration catalog](/docs/category/integrations).
|
|
|
|
### Widgets
|
|
|
|
A **widget** is a board tile. Some widgets work on their own; others require one or more integrations. Configuration,
|
|
supported integrations, and non-obvious limitations are documented on each widget page.
|
|
|
|

|
|
|
|
See the [widget catalog](/docs/category/widgets).
|
|
|
|
### Containers and rails
|
|
|
|
A **Container** groups board items and can be nested. A **rail** reserves a fixed area at the left or right of a
|
|
responsive layout. Both are configured in board edit mode.
|
|
|
|

|
|
|
|
See [Boards](/docs/management/boards#containers-and-rails).
|
|
|
|
### Users, groups, and permissions
|
|
|
|
Users inherit permissions and default boards from their groups. Resource-specific access can further restrict boards
|
|
and integrations.
|
|
|
|

|
|
|
|
See [Users and groups](/docs/management/users) and [single sign-on](/docs/advanced/single-sign-on).
