+See the [DOLFINx README -
+Installation](https://github.com/FEniCS/dolfinx/blob/main/README.md#installation) for
+instructions on installing DOLFINx with petsc4py support.

+Then:
+
+    pip install fenicsx-shells[demos]@git+https://github.com/FEniCS-Shells/fenicsx-shells.git

+At the current time, the `fenicsx-shells` module is empty, and the content of

+custom assemblers.
