+It's unlikely, but not impossible, that there will be breaking changes post-v2.0.0 unless a new major version of Julia is introduced.
 
 You can specify commits, branches or tags in your workflows as follows:
 
 ```yaml
 steps:

+  - uses: julia-actions/setup-julia@v2.0.0  # specific version tag
 ```
 
 If your workflow requires access to secrets, you should always pin it to a commit SHA instead of a tag.
 This will protect you in case a bad actor gains access to the setup-julia repo.

+## Using Dependabot version updates to keep your GitHub Actions up to date
+
+We highly recommend that you set up Dependabot version updates on your repo to keep your GitHub Actions up to date.
+
+To set up Dependabot version updates, create a file named `.github/dependabot.yml` in your repo with the following contents:
+
+```yaml
+version: 2
+updates:
+  - package-ecosystem: "github-actions"
+    directory: "/"
+    schedule:
+      interval: "monthly"
+    open-pull-requests-limit: 99
+    labels:
+      - "dependencies"
+      - "github-actions"
+```
+
+For more details on Dependabot version updates, see the [GitHub Dependabot documentation](https://docs.github.com/en/code-security/dependabot/dependabot-version-updates).
