 For GPU support, we're grateful to use the work of Chainer's `cupy` module,
 which provides a numpy-compatible interface for GPU arrays. However, installing
 Chainer when no GPU is available currently causes an error. We therefore do not

 ```bash
-export CUDA_HOME=/usr/local/cuda-8.0 # Or wherever your CUDA is
-export PATH=$PATH:$CUDA_HOME/bin
-pip install chainer

+Alternatively, to install `cupy` from source use `thinc[cuda]` or install
