docker pull ciriethereum/ciri
Or you can use our prepared rake tasks if you're not familiar with docker:
clone repo and submodules
git clone --recursive https://github.com/ciri-ethereum/ciri.git
cd ciri
make sure we have installed docker, ruby and rake
# make sure we have installed docker, ruby and rake
docker -v
gem install rake

rake docker:pull
# run tests
rake docker:spec
# run specific component related tests
rake docker:spec[component_name]
# open a shell for developing
rake docker:shell
# build Ciri docker image from current source (it will take a few minutes)
rake docker:build
# type 'rake -T' see other supported tasks
rake -T
