+## Firmware updates
+
+As of Qubes 4.2, firmware updates can be performed from within Qubes for [fwupd-supported computers](https://fwupd.org/).
+
+### In dom0
+
+First, ensure that your [UpdateVM](/doc/Software/UpdateVM/)
+contains the `fwupd-qubes-vm` package. This package is installed
+by default for qubes with `qubes-vm-recommended` packages.
+
+In a dom0 terminal, install the `fwupd-qubes-dom0` package:
+
+  ```
+  $ sudo qubes-dom0-update fwupd-qubes-dom0
+  ```
+
+Once the package is installed:
+
+   ```
+   $ sudo qubes-fwupdmgr get-devices
+   ```
+
+Examine the terminal output for warnings or errors.
+You may see the following warning:
+
+   ```
+   WARNING: UEFI capsule updates not available or enabled
+   ```
+If so, [adjust your BIOS settings](https://github.com/fwupd/fwupd/wiki/PluginFlag:capsules-unsupported) to enable UEFI updates. This setting is sometimes named "Windows UEFI Firmware Update."
+
+Once resolved, in a dom0 terminal:
+
+  ```
+  $ sudo qubes-fwupdmgr get-devices
+  $ sudo qubes-fwupdmgr refresh
+  $ sudo qubes-fwupdmgr update
+  ```
+
+A numbered list of devices with available updates will be presented. Ensure your computer is plugged in to a stable power source, then type the list number of the device you wish to update. If a reboot is required, you will be prompted at the console to confirm.
+
+Repeat the update process for any additional devices on your computer.
+
+### In other qubes
+
+Devices that are attached to non-dom0 qubes can be updated via a graphical tool for `fwupd`, or via the `fwupdmgr` commandline tool.
+
+To update the firmware of offline qubes, use the [Updates
+proxy](/doc/how-to/install/software/#updates-proxy).
+
+### Computers without fwupd support
+
+For computers that do not have firmware update support via `fwupd`, follow the firmware update instructions on the manufacturer's website. Verify the authenticity of any firmware updates you apply.
