$ cargo dist init --installer homebrew
let's setup your cargo-dist config...

✔ what platforms do you want to build for?
    (select with arrow keys and space, submit with enter) · Linux x64 (x86_64-unknown-linux-gnu), macOS Apple Silicon (aarch64-apple-darwin), macOS Intel (x86_64-apple-darwin), Windows x64 (x
86_64-pc-windows-msvc)
✔ enable Github CI and Releases? · yes

✔ check your release process in pull requests? · plan - run 'cargo dist plan' on PRs (recommended)

✔ what installers do you want to build?
    (select with arrow keys and space, submit with enter) · homebrew

✔ you've enabled Homebrew support; if you want cargo-dist
    to automatically push package updates to a tap (repository) for you,
    please enter the tap name (in GitHub owner/name format) · daido1976/homebrew-tap

✔ Homebrew package will be published to daido1976/homebrew-tap
✔ You must provision a GitHub token and expose it as a secret named
    HOMEBREW_TAP_TOKEN in GitHub Actions. For more information,
    see the documentation:
    https://opensource.axo.dev/cargo-dist/book/installers/homebrew.html

✔ added [profile.dist] to your root Cargo.toml
✔ added [workspace.metadata.dist] to your root Cargo.toml
✔ cargo-dist is setup!

+# This task will run whenever you push a git tag that looks like a version
+# like "1.0.0", "v0.1.0-prerelease.1", "my-app/0.1.0", "releases/v1.0.0", etc.
+# Various formats will be parsed into a VERSION and an optional PACKAGE_NAME, where
+# PACKAGE_NAME must be the name of a Cargo package in your workspace, and VERSION
+# must be a Cargo-style SemVer Version (must have at least major.minor.patch).
+#
+# If PACKAGE_NAME is specified, then the release will be for that
+# package (erroring out if it doesn't have the given version or isn't cargo-dist-able).
+#
+# If PACKAGE_NAME isn't specified, then the release will be for all
+# (cargo-dist-able) packages in the workspace with that version (this mode is
+# intended for workspaces with only one dist-able package, or with all dist-able
+# packages versioned/released in lockstep).
+#
+# If you push multiple tags at once, separate instances of this workflow will
+# spin up, creating an independent Github Release™ for each one. However Github
+# will hard limit this to 3 tags per commit, as it will assume more tags is a
+# mistake.
+#
+# If there's a prerelease-style suffix to the version, then the Github Release™
+# will be marked as a prerelease.
