 ## Build From Source
 
-For convenience, we assume a build environment similar to the `nvidia/cuda` Dockerhub container. As of writing, the latest container is `nvidia/cuda:11.6.2-cudnn8-devel-ubuntu20.04`. Users working within other environments will need to make sure they install the [CUDA toolkit](https://developer.nvidia.com/cuda-toolkit) and [CUDNN](https://developer.nvidia.com/cudnn) and [NCCL](https://developer.nvidia.com/nccl) libraries separately.

-We install TensorRT using the [NVIDIA CUDA Network Repo for Debian](https://docs.nvidia.com/deeplearning/tensorrt/install-guide/index.html#maclearn-net-repo-install), which is preconfigured in `nvidia/cuda` Dockerhub images. Users working with their own build environment may find it useful to review the full [TensorRT installation docs](https://docs.nvidia.com/deeplearning/tensorrt/install-guide/index.html#installing).
