# self-update

> Upgrade the Crewship binary from a released installation.

## `crewship self-update`

Checks for and installs the latest release. Homebrew installations use
Homebrew; installer/tarball installations download and verify the matching
asset. Development builds cannot self-update.

```bash theme={null}
crewship self-update --check
crewship self-update
crewship self-update --systemd --service crewship --health-timeout 60s
```

`--check` makes no changes. `--systemd` orchestrates stop → replace → start →
health-check and automatically rolls back when startup or health checks fail.
Additional options include `--service`, `--health-url`, and `--port`.
