 The CUDA and python versions can be changed for the supported values:
-- Supported CUDA versions: 11.4 and 12.x
-- Supported Python versions: 3.9 and 3.10.
+- Supported CUDA versions: 11.8 and 12.5
+- Supported Python versions: 3.10 and 3.11.

 **Note:** GPU containers use the CUDA toolkit from inside the container, the only requirement is a driver installed on the host machine that supports that version. So, for example, CUDA 11.8 containers can run in systems with a CUDA 12.x capable driver. Please also note that the Nvidia-Docker runtime from the `Nvidia Container Toolkit <https://github.com/NVIDIA/nvidia-docker>`_ is required to use GPUs inside docker containers.
 
-How to run the benchmarks

+How benchmarks are run

+The `cuvs-bench` package contains lightweight Python scripts to run the benchmarks. There are 4 general steps to running the benchmarks and visualizing the results.
