Ready-to-paste prompt

cabal run cardano-cli --generate-genesis-json > genesis.json

Heads up: The Cardano-sl project requires a specific version of the Glasgow Haskell Compiler (GHC) and may not work with the latest version, so ensure you're using a compatible GHC version before building the project
