## 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"
|
|
```
|
|
|
|
