 The library depends on the Python-interface of [DOLFINx](https://github.com/) and an MPI-build of [ADIOS2](https://adios2.readthedocs.io/en/latest/setting_up/setting_up.html#as-package).
 Therefore `ADIOS2` should not be install through PYPI/pip, but has to be installed through Conda, Spack or from source.
 
+> [!IMPORTANT]  
+> ADIOS2<2.10.2 does not work properly with `numpy>=2.0.0`. Everyone is adviced to use the newest version of ADIOS2.
+> This is for instance available through `conda` or the `ghcr.io/fenics/dolfinx/dolfinx:nightly` Docker-image.

 ### Docker
 
 An MPI build of ADIOS2 is installed in the official DOLFINx containers, and thus there are no additional dependencies required to install `adios4dolfinx`
