+Control and Telemetry Systems (CATS) builds open source (hardware and software) flight computers for sounding rockets. Our portfolio includes the _CATS Vega_ flight computer and the _CATS Ground Station_ that can be connected to the flight computer over telemetry. The flight computer can easily be configured through the _CATS Configurator_, a desktop application. The system allows the user to configure up to 8 actions per flight transition, giving full control over the flight and a safe recovery of your rocket.
 
 ## Features
 * Kalman filter altitude and velocity estimation
-* Triple sensor redundancy
-* Highly configurable events
+* Highly configurable events (up to eight actions per flight state transition)
 * Backup timers
-* High speed logging
+* High speed logging (up to 100 Hz)
+* Telemetry with a range of at least 10 km
+* GNSS logging and transmission to the ground station
+* Accelerometric liftoff detection
+* Fully open source
+* Configuration is done over our application, no need to work with a CLI
 
 ## Configuration Tool
-Currently, the configuration tool is still under development. An initial version can be downloaded [here](https://github.com/catsystems/cats-configurator/releases).
+The CATS Configurator is in beta. More features will be released in the near future. It can be downloaded [here](https://github.com/catsystems/cats-configurator/releases). A description of the configurator can be found in the [CATS User Manual](https://github.com/catsystems/cats-embedded/raw/main/CATS%20User%20Manual.pdf).

+## Overview
+Here is a quick overview of our system, in the form of a poster that we presented at the [26th ESA PAC Symposium](https://atpi.eventsair.com/26th-esa-pac-symposium/).
