## Keep up-to-date with GitHub Dependabot
Since [Dependabot ](https://docs.github.com/en/github/administering-a-repository/keeping-your-actions-up-to-date-with-github-dependabot )
has [native GitHub Actions support ](https://docs.github.com/en/github/administering-a-repository/configuration-options-for-dependency-updates#package-ecosystem ),
to enable it on your GitHub repo all you need to do is add the `.github/dependabot.yml` file:
```yaml
version: 2
updates:
# Maintain dependencies for GitHub Actions
- package-ecosystem: "github-actions"
directory: "/"
schedule:
interval: "daily"
```
