## プロジェクトの歴史と使われ方

Countdown is a small Go terminal countdown timer distributed as a command-line utility.

### プロジェクトの歴史

The public repository was created in 2019 and describes a focused CLI for countdowns, target times, count-up mode, titles, pausing, and optional macOS speech announcements.

### 採用の歴史

The official install instructions name Homebrew, `go install`, and prebuilt GitHub release binaries, which is the typical distribution mix for a compact Go CLI.

### 使われ方

Users invoke `countdown` with a Go-style duration or a target time, optionally chaining a shell command after completion.

### パッケージ好きにとっての重要性

Its packaging is intentionally simple: one executable, no documented config file, and release artifacts suitable for Homebrew-style formula maintenance.

### タイムライン

- 2019: Public GitHub repository created and 1.0.0 release published.
