+The `subminer` launcher handles video selection, mpv startup, and overlay management in one script. Use it on Linux and macOS: it is the only path that guarantees mpv comes up with the right IPC socket and SubMiner's defaults. It is a Bun script, shipped as a release asset next to the AppImage and DMG.
 
 ::: tip Windows users
 On Windows, the recommended way to launch playback is the **SubMiner mpv** shortcut created during first-run setup - double-click it, drag a file onto it, or run `SubMiner.exe --launch-mpv` from a terminal. See [Windows mpv Shortcut](/usage#windows-mpv-shortcut) for details.

-## Sync Between Machines
+## Sync between machines
 
 `subminer sync <host>` merges immersion stats and watch history between two machines over SSH, so both end up with the union of sessions, lifetime totals, vocabulary counts, daily/monthly charts, and `--history` entries. `<host>` is anything `ssh` accepts (`user@hostname` or an ssh config alias); SubMiner must be installed on both machines at the same version. The sync engine runs only inside the app (`SubMiner --sync-cli sync ...`): the sync window spawns it that way, `subminer sync` is a thin proxy that forwards to the installed app, and the remote side is found automatically whether it has the launcher or just the app. The command-line launcher is optional everywhere.

 Hosts with **Auto-sync** enabled are synced in the background on a configurable interval (default every 60 minutes), including during active playback; results surface as overlay notifications. The unfinished playback session is skipped until a later sync sees it finalized. Host bookkeeping lives in `<config dir>/sync-hosts.json`.
