 Requires:
-- [NumPy](https://numpy.org/)
+- [NumPy](https://numpy.org/) (>= 1.21, < 3)
+- [Suzuki-Trotter-Evolver](https://github.com/Christopher-K-Long/Suzuki-Trotter-Evolver) (== 1.1.0, packaged with PySTE)
+- [Eigen3](https://eigen.tuxfamily.org/) (== 3.4.90, packaged with PySTE)
 
 Note that [Suzuki-Trotter-Evolver](https://github.com/Christopher-K-Long/Suzuki-Trotter-Evolver) and [Eigen3](https://eigen.tuxfamily.org/) are packaged with PySTE and so do not need to be installed separately.

Increasing the number of optimised evolvers increases the compile time. The ``--verbose`` flag allows the progress of the build to be seen. This is useful as the builds can often take a long time.
+will build PySTE from source and optimises evolvers at compile time with 2 control Hamiltonians acting on a vector space of dimensions 2, 4, and 8. Increasing the number of optimised evolvers increases the compile time. The ``--no-binary py-ste`` flag instructs ``pip`` to build ``py-ste`` from source and the following ``py-ste`` instructs ``pip`` that ``py-ste`` is one of the packages to collect (indeed the only package). The ``--no-cache-dir`` flag ensures that a cached ``.whl`` file is not used instead and the package is actually built from source. Finally, the ``--verbose`` flag allows the progress of the build to be seen. This is useful as the builds can often take a long time.
 
 *Note building from source requires approximately 16GB of RAM.*
