# build a network of eth2 nodes using geth + pryms
# please check the workflows/manual-deploy-testnet-l1.yml for more info

# Build Stages:
# system = prepares the "OS" by downloading required binaries
# get-dependencies = downloads the go modules using the prepared system
# build-geth-binary = runs the build_geth_binary script once 'system' stage is finished
# build-geth-network = compiles the gethnetwork obscuro project when 'get-dependencies' stage is finished
# final = copies over the executables from the 'build-*' stages and prepares the final image.
