+This firmware offers a library of hardware and software functionality targeting the use of the Stabilizer hardware in various digital signal processing applications commonly occurring in Quantum Technology applications.
+It provides abstractions over the fast analog inputs and outputs, time stamping, Pounder DDS interfaces and a collection of tailored and optimized digital signal processing algorithms (IIR, FIR, Lockin, PLL, reciprocal PLL, Unwrapper, Lowpass, Cosine-Sine, Atan2).
+An application can compose and configure these hardware and software components to implement different use cases.

+* Install `probe-run`: `cargo install probe-run`
+* `cargo run --release --bin dual-iir`
 * When using debug (non `--release`) mode, increase the sample interval significantly.
   The added error checking code and missing optimizations may lead to the code
   missing deadlines and panicing.

 Stabilizer can be configured via MQTT. Refer to
 [`miniconf`](https://github.com/quartiq/miniconf) for more information about topics.
 A basic command line interface is available in [`miniconf.py`](miniconf.py).
+Telemetry is published via MQTT as well.
