 This library makes it easy to use the multi-threading capability of [Arduino](https://www.arduino.cc/) boards that use an [Mbed OS](https://os.mbed.com/docs/mbed-os/latest/introduction/index.html)-based core library.
+
+## :zap: Features
+### :thread: Multi-threaded sketch execution
+Instead of one big state-machine-of-doom you can split your application into multiple independent threads, each with it's own `setup()` and `loop()` function. Instead of implementing your application in a single `.ino` file, each independent thread is implemented in a dedicated `.inot` representing a clear separation of concerns on a file level.
+
+### :calling: Easy communication between multiple threads
+Easy inter-thread-communication is facilitated via a `Shared` abstraction providing thread-safe sink/source semantics allowing to safely exchange data of any type between threads.

+## :yellow_heart: Donations
+
+This open-source code is maintained by Arduino with the help of the community. We invest a considerable amount of time in testing code, optimizing it and introducing new features. Please consider [donating](https://www.arduino.cc/en/donate/) or [sponsoring](https://github.com/sponsors/arduino) to support our work, as well as [buying original Arduino boards](https://store.arduino.cc/) which is the best way to make sure our effort can continue in the long term.
