# README!
# Every time you modify the `cabal.project`, you have to make sure to update
# the `expected_cabal_project_hash` and `expected_cabal_project_freeze_hash`
# with the `sha256sum` result calculated on the `cabal.project` and
# `cabal.project.freeze`. This ensures the files stay deterministic so that CI
# cache can kick in.
