-Mat3ra is a platform for materials modeling from the atoms up. This documentation explains how to use the platform to
-design new materials and predict their properties using physics-based and AI/ML models powered by cloud HPC.
+Mat3ra.com offers a comprehensive high-performance computing (HPC) solution in
+the cloud with a special focus on materials simulation for both academia and
+industry. We offer an intuitive web interface for designing new materials,
+managing workflows, running simulations, and organizing results and data in a
+more collaborative, accessible, and efficient way.
+
+Certainly, the command line interface (CLI) will remain a powerful choice among
+the advanced HPC users, so not only do we offer SSH connection to our platform,
+but we also offer a web terminal feature that can be used from any web browser
+on any device without the need for an SSH client or terminal application.
+
+Finally, we offer API access to our platform that allows integrating our
+platform features with other tools and applications, including access from
+within the Python Jupyter Notebook, a popular tool among data scientists and
+machine learning engineers.
+
+We are here to be part of your journey to accelerate your R&D on materials
+design and discovery in the AI/ML era. This documentation explains how you can
+use our platform to design new materials and simulate their properties using
+physics-based and AI/ML models powered by cloud HPC.
