## What it is
RocketPy is a Python library for high-fidelity 6-DOF trajectory simulation of high-power rockets, including variable mass effects, parachute descent, and weather/wind data integration. It supports multi-stage rockets, dispersion analysis, and trajectory optimization.

## Use cases
- simulate a high-power rocket flight trajectory in 6 degrees of freedom
- model parachute descent and landing for a rocketry competition
- run Monte Carlo dispersion analysis on rocket flight predictions
- import wind and weather profiles into a flight simulation
- optimize rocket design and trajectory for apogee targets
- simulate multi-stage rocket flights with variable mass effects

## When to choose
- you need physics-based 6-DOF rocket trajectory simulation in Python
- you want realistic wind/weather data integration and parachute descent modeling
- you need dispersion analysis or trajectory optimization for rocketry projects

## When to avoid
- you need a GUI-based rocket simulator rather than a Python library
- you are simulating orbital spacecraft rather than atmospheric sounding rockets
- you need real-time flight control software rather than pre-flight simulation
