# bt update

> Update the bt CLI binary in place.

`bt update` updates the CLI binary in place. It works for installs made with the standalone shell or PowerShell installer.

```bash theme={"theme":{"light":"github-light","dark":"github-dark-dimmed"}}
bt update
bt update --check
bt update --channel canary
```

If you installed `bt` with [mise](/docs/reference/cli/quickstart#install-with-mise) or [npm](/docs/reference/cli/quickstart#install-with-npm), update `bt` with that package manager instead.
