# Core concepts: dashboards, tiles, modules, and more

> Learn the key terms in Relay so the rest of the docs makes immediate sense.

Relay has a small set of building blocks that appear throughout the app and these docs. Understanding them first makes everything else easier to follow.

<AccordionGroup>
  <Accordion title="Dashboard">
    A dashboard is the top-level Relay document. It contains all of your tabs, tiles, modules, and automation configuration. Dashboards are typically saved as `.relay` files and can be opened, backed up, or shared like other files on your Mac.
  </Accordion>

  <Accordion title="Tab">
    A tab is a page inside a dashboard. Each tab has its own canvas and tile arrangement. Tabs are useful for separating different roles, different production moments, or different event segments inside one dashboard file.
  </Accordion>

  <Accordion title="Canvas">
    The canvas is the workspace inside a tab where you place and arrange tiles. Canvas View is the editing mode you use before and between events. It supports moving, resizing, aligning, and grouping content visually.
  </Accordion>

  <Accordion title="Tile">
    A tile is a movable, resizable container on the canvas. Every piece of dashboard content lives inside a tile. A tile can hold one module or multiple modules depending on how you want the layout grouped.
  </Accordion>

  <Accordion title="Module">
    A module is the actual content inside a tile. Examples include Planning Center, Person, ProPresenter, Shure, SPL Meter, Live Transcription, Text, Document, Webpage, Time, and Button.
  </Accordion>

  <Accordion title="Live Mode">
    Live Mode is the focused operating mode designed for real use during a show or service. It reduces editing controls and is where many live-updating workflows are expected to run.
  </Accordion>

  <Accordion title="Automation View">
    Automation View is the node-based editor where you connect triggers, actions, utilities, and destinations. It lets Relay respond to incoming events and control connected systems without requiring code.
  </Accordion>

  <Accordion title="Relay Pro">
    Relay Pro is the paid tier that unlocks advanced modules, integrations, and workflows. If a feature appears locked, check your status in `Relay > Settings > License` and refresh your license if needed.
  </Accordion>

## Dashboard files

Relay dashboards are normally saved as `.relay` files. Older `.pld` files may still be supported for opening existing work. If a dashboard already has a file location, Relay can also autosave changes back to it when autosave is enabled in settings.
