+      openMotor is an open-source internal ballistics simulator for rocket motor
+      experimenters. The software estimates a rocket motor's chamber pressure and
+      thrust based on propellant properties, grain geometry, and nozzle specifications.
+      It uses the Fast Marching Method to determine how a propellant grain regresses,
+      which allows the use of arbitrary core geometries.
