 ## CUDA enabled variant
 
 We provide CUDA accelerated version of `pytorch-notebook` and `tensorflow-notebook` images.
-Prepend a CUDA version prefix (like `cuda12-` for `pytorch-notebook` or `cuda-` for `tensorflow-notebook`) to the image tag
+Prepend a CUDA prefix (versioned prefix like `cuda12-` for `pytorch-notebook` or just `cuda-` for `tensorflow-notebook`) to the image tag
 to allow PyTorch or TensorFlow operations to use compatible NVIDIA GPUs for accelerated computation.
 Note: We only build `pytorch-notebook` for 2 last major versions of CUDA, `tensorflow-notebook` image only supports the latest CUDA version listed in the [officially tested build configurations](https://www.tensorflow.org/install/source#gpu).
