+## Running in Docker
+See example Dockerfile (works on machine where you can pass the gpu into the container)
+```bash
+docker build . -t imaginairy
+# you really want to map the cache or you end up wasting a lot of time and space redownloading the model weights
+docker run -it --gpus all -v $HOME/.cache/huggingface:/root/.cache/huggingface -v $HOME/.cache/torch:/root/.cache/torch -v `pwd`/outputs:/outputs imaginairy /bin/bash
