+## ASTOS Documentation - Sub-Orbital Rocket Trajectory Modelling
+
+This repository contains a few documents for covering how to create a trajectory simulation in ASTOS.
+
+1. UI Overview - Pictorial descriptions of the UI in ASTOS
+2. Model Setup - Covers the nuts and bolts of setting up the model in ASTOS
+3. Results Analysis - Pictorial descriptions of getting result output as well as data extraction to Excel format
+
+For a deeper understanding of the models within ASTOS, the <a href="ASTOS Reference/Model_Reference.pdf">ASTOS model reference</a> is available.
