# Updates

> Keep your N.O.M.A.D. software and installed apps up to date.

N.O.M.A.D. has two distinct update paths: **software updates** for the Command Center itself, and **content and app updates** for the tools and data you've installed. Both are managed from within the Settings area.

<Tip>
  Run updates while you have internet access. Once you go offline, you can't pull new versions until you reconnect.
</Tip>

## Software updates

Software updates upgrade the N.O.M.A.D. Command Center and its core dependencies.

### Checking for and installing an update

<Steps>
  <Step title="Open the update page">
    Go to **Settings → Check for Updates**.
  </Step>

  <Step title="Check for available updates">
    The page shows your current version and checks whether a newer release is available.
  </Step>

  <Step title="Install the update">
    If an update is available, click to install it. N.O.M.A.D. downloads the update and restarts automatically.
  </Step>

  <Step title="Wait for the restart to complete">
    The server restart typically takes **2–5 minutes**. Your browser connection will drop briefly during the restart — this is expected. Refresh the page after a minute or two to reconnect.
  </Step>
</Steps>

<Note>
  If an update fails, the previous version should continue running. Try again later, or check **Settings → System** for any error messages.
</Note>

## Early Access Channel

The Early Access Channel lets you opt in to receive release candidate builds — the latest features and improvements before they reach the stable release.

To enable it, go to **Settings → Check for Updates** and turn on the Early Access Channel toggle.

<Warning>
  Early access builds may contain bugs. If you need maximum stability, stay on the stable channel. You can switch back to stable from the same page at any time.
</Warning>

## App updates

Installed apps (AI Assistant, Information Library, Education Platform, etc.) are updated separately from the core software.

Starting in **v1.29**, N.O.M.A.D. automatically checks for newer versions of your installed apps each night. When updates are available, notifications appear on the **Settings → Apps** page.

### Applying an app update

<Steps>
  <Step title="Open the Apps page">
    Go to **Settings → Apps**.
  </Step>

  <Step title="Find tools with available updates">
    Tools with pending updates are flagged with an update indicator. Select the version you want to apply.
  </Step>

  <Step title="Apply the update">
    Click the update action. N.O.M.A.D. pulls the updated container image and recreates the container. The tool is briefly unavailable during the process.
  </Step>
</Steps>

See [Apps Manager](/management/apps) for full details on managing installed tools.

## Content updates

Content updates (Wikipedia snapshots, map regions, ZIM files) are managed separately:

* **ZIM content** (Wikipedia, references, ebooks) — update via **Settings → Content Explorer**. Check for newer versions of your installed files and download them.
* **Map regions** — map data does not have an automatic update check. Re-download a region from **Settings → Maps Manager** to get the latest version.
* **Educational content** — Kolibri manages its own content channels. Open Kolibri, sign in as admin, and go to **Device → Channels** to update course content.
