Follow normal docker installation. Start docker container with binds to src/ and dist/:
docker run -v $(pwd)/results:/root/CryptOpt/results -v $(pwd)/src:/root/CryptOpt/src -v $(pwd)/test:/root/CryptOpt/test --name CryptOpt -ti cryptopt zsh
Inside container: make watch
Connect in another terminal to the container: docker exec -it CryptOpt /bin/zsh and execute CryptOpt from there
