+              The NIH-funded TOPAS project made radiation therapy simulations using the Monte Carlo method easily
+              accessible for the radiotherapy community. This repository brings the code to a new, truly open
+              release stage called <strong>OpenTOPAS</strong>.
+            </p>
+            <p>
+              OpenTOPAS wraps and extends the <a href="https://geant4.web.cern.ch" target="_blank" rel="noopener">Geant4 Simulation Toolkit</a>
+              to provide an easier-to-use application for the medical physicist. The parameter control system lets physicists assemble and control a rich
+              library of simulation objects—geometry components, particle sources, scorers—without writing C++ or knowing Geant4 internals.
+              Visit the <a href="https://opentopas.readthedocs.io/en/latest" target="_blank" rel="noopener">User Guide</a> for deeper dives.
+            </p>
+            <p>
+              The project was originally created out of an NIH-funded collaboration of Massachusetts General Hospital,
+              University of California San Francisco, and SLAC National Accelerator Laboratory. Today, the UCSF and MGH teams continue
+              to maintain and expand OpenTOPAS in partnership with the Monte Carlo community.
+            </p>
+            <p>
+              OpenTOPAS supports simulation of medical applications of ionizing radiation with the Monte Carlo method.
+              Free availability is intended to aid research by medical physicists, radiobiologists, and clinicians across all radiotherapy modalities.
+              New users should review the key publications to explore its potential.
