+  `nomad-simulations` is a plugin for the NOMAD software (https://zenodo.org/doi/10.5281/zenodo.8366162)
+  providing a common data standard and analysis tools for parsed Materials Science and Quantum Chemistry
+  simulations. This standard is used as a template and is populated by the many available NOMAD parsers to transform their
+  inputs / outputs into a structured data format. This plugin is community-driven, and users are encourage to
+  contribute towards providing Findable, Accessible, Interoperable, and Reusable (FAIR) data.

 # `nomad-simulations`
 
-This is a plugin for [NOMAD](https://nomad-lab.eu) which contains the base sections definitions for materials science simulations. This schema can be used at any prefered level by the user, it can be modified and extended, and we welcome external collaborators.
+The `nomad-simulations` is an open-source Python package for managing Materials Science simulation data. It is following the plugin architechture of [NOMAD](https://nomad-lab.eu). This package contains a set of section definitions (Python classes) with quantities (attributes) and methods defined to automate data extraction from different simulation codes. These section definitions can be used at any prefered level by the user, they can be modified and extended, and we welcome external collaborators.

 `nomad-simulations` can be installed as a PyPI package using `pip`:
