+# Firmware
+
+Occasionally, changes and improvements to the system software (firmware) on the @boardname@ are needed. Updates to the firmware are made by the [micro:bit Education Foundation](http://microbit.org/about).

+## Do I need an update?

+Changes to the firmware don't happen very often. You probably don't need to update it for your @boardname@ if everything is working alright. Sometimes there's a problem with a certain part of the board not working right or it has trouble connecting to your computer or other device. In those cases, a firmware update may include a fix for the problem.
+
+## Getting a firmware update

+Instructions for updating the firmware are shown on the **[firmware upgrade](https://support.microbit.org/support/solutions/articles/19000019131-how-to-upgrade-the-firmware-on-the-micro-bit)** support page at microbit.org.
