 Currently, only single-GPU calculations are supported, but a multi-GPU execution will be
 implemented in the due course using `mpi4py` library.
 
 ## Getting started
 
 `pytket-cutensornet` is available for Python 3.9, 3.10 and 3.11 on Linux.
-In order to use it, you need access to a Linux machine with either `Volta`, `Ampere`
-or `Hopper` GPU and first install `cuQuantum Python` following their installation
