Overview

The contributors table has been generated using the all-contributors cli tool. It lists any one who provided substantial efforts to the software side of the Asterius project. This includes but is not limited to: anyone who contributed code even if one line or a launch file, anyone who helped write code indirectly such as by providing calculations and advice during a working session
