 The DeckSurf SDK is used to manage Stream Deck devices and create plugins for [DeckSurf tools](https://github.com/dend/DeckSurf). It is completely independent of the Elgato software and/or libraries and can be used as a standalone library.
 
+## Supported devices
+
+Support for the following devices is implemented:
+
+- Stream Deck XL
+- Stream Deck Plus
+
+Future support is coming for:
+
+- Stream Deck Neo
+- Stream Deck Mini
+- Stream Deck MK.2
+- Stream Deck Original V2
+
+## Documentation
+
+Refer to [`https://docs.deck.surf`](https://docs.deck.surf/) for tutorials and SDK documentation.

 ## Platform compatibility
 
 The SDK in its current implementation has a number of dependencies on Windows APIs, therefore will only work on Windows. In future releases, I am thinking of a way to rip out native components and separate them in their own package, allowing the SDK to be fully cross-platform.
