+
+`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
+
+Using **conda**:
+
+```bash
+conda create -n openmc2dolfinx-env
+conda activate openmc2dolfinx-env
+conda install -c conda-forge fenics-dolfinx=0.9.0 mpich pyvista
+```
+Once in the created in environment:
+```bash
+python -m pip install openmc2dolfinx
+```
+
+## Example usage
 
-## Usage
 ```python
 from openmc2dolfinx import StructuredGridReader, UnstructuredMeshReader
 import pyvista as pv
