-`openmc2dolfinx` is a tool for converting OpenMC output `.vtk` files to functions that can be used within [dolfinx](https://github.com/FEniCS/dolfinx).
+`openmc2dolfinx` is a lightweight tool for converting [OpenMC](https://github.com/openmc-dev/openmc) output data (in `.vtk` format) into [dolfinx](https://github.com/FEniCS/dolfinx)-compatible `fem.Function` objects.
+It is primarily designed to facilitate multiphysics coupling between OpenMC and finite element simulations (e.g. thermal, diffusion, or tritium transport analyses).
+
+## Key features
+
+ - Convert structured and unstructured VTK meshes to dolfinx meshes.
+ - Interpolate OpenMC tally results directly into dolfinx Function spaces.
+ - Integrated with PyVista for mesh and data inspection.
 
 ## Installation
