+With the solid technical foundation of Zephyr™ RTOS, ZMK can support a wide diversity of hardware targets.
+That being said, there are currently only a few specific [boards](/docs/faq#what-is-a-board)/[shields](faq.md#what-is-a-shield) that have been implemented and tested by the ZMK contributors.

+
+## Other Hardware
+
+In addition to the basic keyboard functionality, there is some initial support for additional keyboard hardware:
+
+- Encoders
+- Displays
+- RGB Underglow
+
+Until detailed documentation is available, feel free to ask questions about how these are supported in the [Discord server](https://zmk.dev/community/discord/invite).

+## Contributing
