Sure, here's the Makefile. Also, if you want more examples of working Hakyll setups, there's a long list of them here: https://jaspervdj.be/hakyll/examples.html

    # Binary tool we use to build the website.
    bins = dist-newstyle/build/*/*/*/*/site/build/site
    tool = $(bins)/site

    # By default, we build everything if you invoke `make` without a target.
    all: build
    .PHONY: all

    # The tool used to build the site is a Hakyll binary configured by `site.hs`.
    # This rule automatically builds the tool if it's out of date.
    $(tool): site.hs site.cabal
            cabal v2-build

    # The `build` target builds the web site's out-of-date static assets.
    .PHONY: build
    build: $(tool) pdfs
            $(tool) build

    # The `rebuild` target forces a rebuild of all web assets.
    .PHONY: rebuild
    rebuild: $(tool)
            $(tool) rebuild

    # This `push` rule publishes the static site to our CDN (firebase).
    # It requires:
    #
    # - the `firebase` tool:
    #   wget -O ~/bin/firebase https://firebase.tools/bin/linux/latest \
    #       && chmod +x ~/bin/firebase
    #   # Docs: https://firebase.google.com/docs/cli#linux
    #
    # - `firebase login --no-localhost` to have been run.
    #
    # You may need to run `firebase login --no-localhost --reauth` if
    # the local authentical credentials time out.
    .PHONY: push
    push: build
            firebase deploy --only hosting

    # Generate PDF versions of selected blog posts.
    .PHONY: pdfs
