          **Bose SoundTouch Toolkit.** Keep your Bose SoundTouch speakers alive after the Bose cloud shutdown. No Bose infrastructure required.

          ## What's included

          Pre-built binaries for Linux (amd64, arm64, armv7), macOS (Intel & Apple Silicon), Windows (amd64), and FreeBSD (amd64):

          - **soundtouch-service**: local server that replaces the Bose cloud. Point your speaker at it and you keep full control; the built-in web UI on port 8000 handles setup.
          - **soundtouch-player**: standalone LAN web UI for device control: play/pause, volume, presets, live status. (Formerly \`soundtouch-web\`.)
          - **soundtouch-cli**: command-line control of any device: playback, presets, sources, multiroom zones, discovery, and migration. Good for scripting and home automation.
          - **soundtouch-backup**: back up your Bose cloud account and each speaker's local state. \`soundtouch-backup all\` captures everything in one step.

          Not sure which file to grab? The [Downloads page](https://gesellix.github.io/Bose-SoundTouch/docs/downloads/) explains which tool you need and which \`<os>-<arch>\` build matches your computer.

          ## Documentation

          Full guides, setup walkthroughs, and troubleshooting: https://gesellix.github.io/Bose-SoundTouch/

          ## Use as a Go library

          The core client is also importable:

          \`\`\`bash
          go get github.com/gesellix/bose-soundtouch@$TAG_NAME
          \`\`\`

          ## Verifying downloads

          Each binary has its own \`.sha256\`/\`.sha512\`, and combined \`checksums.sha256\` / \`checksums.sha512\` cover all of them:

          \`\`\`bash
          sha256sum -c checksums.sha256 --ignore-missing
          \`\`\`
