 GOOS=darwin GOARCH=amd64 go build -o blah_darwin64

   --a-thousand-params ▸ Snaps ▸ snapcraft --another-thousand-params config.yml

9. RELEASING HOMEBREW ▸ Homebrew core ▸ Harder to get things

   in there: licensing, replicating dependencies into the recipe, etc ▸ brew install mytool ▸ Homebrew taps ▸ brew install caarlos0/tap/mytool

10. RELEASING DOCKER ▸ FROM scratch
 COPY mybin /
 ENTRYPOINT ["/mybin"]

    ▸ docker build -t user/img:tag . ▸ docker tag user/img:tag user/img:latest ▸ docker push user/img:tag ▸ docker push user/img:latest

11. RELEASING GITHUB RELEASES ▸ git tag && git push ▸

    Upload artifacts ▸ Generate and upload checksums maybe ▸ Edit the release notes
