+### Using Microsoft distribution on GHES
+
+`setup-java` comes pre-installed on the appliance with GHES if Actions is enabled. When dynamically downloading the Microsoft Build of OpenJDK distribution, `setup-java` makes a request to `actions/setup-java` to get available versions on github.com (outside of the appliance). These calls to `actions/setup-java` are made via unauthenticated requests, which are limited to [60 requests per hour per IP](https://docs.github.com/en/rest/overview/resources-in-the-rest-api#rate-limiting). If more requests are made within the time frame, then you will start to see rate-limit errors during downloading that looks like: `##[error]API rate limit exceeded for...`.
+
+To get a higher rate limit, you can [generate a personal access token on github.com](https://github.com/settings/tokens/new) and pass it as the `token` input for the action:
+
+```yaml
+uses: actions/setup-java@v3
+with:
+  token: ${{ secrets.GH_DOTCOM_TOKEN }}
+  distribution: 'microsoft'
+  java-version: '11'
+```
+
+If the runner is not able to access github.com, any Java versions requested during a workflow run must come from the runner's tool cache. See "[Setting up the tool cache on self-hosted runners without internet access](https://docs.github.com/en/enterprise-server@3.2/admin/github-actions/managing-access-to-actions-from-githubcom/setting-up-the-tool-cache-on-self-hosted-runners-without-internet-access)" for more information.

 ## Hosted Tool Cache
 GitHub Hosted Runners have a tool cache that comes with some Java versions pre-installed. This tool cache helps speed up runs and tool setup by not requiring any new downloads. There is an environment variable called `RUNNER_TOOL_CACHE` on each runner that describes the location of this tools cache and this is where you can find the pre-installed versions of Java. `setup-java` works by taking a specific version of Java in this tool cache and adding it to PATH if the version, architecture and distribution match.
 
-Currently, LTS versions of Adopt OpenJDK (`adopt`) are cached on the GitHub Hosted Runners.
+Currently, LTS versions of Eclipse Temurin (`temurin`) are cached on the GitHub Hosted Runners.
 
 The tools cache gets updated on a weekly basis. For information regarding locally cached versions of Java on GitHub hosted runners, check out [GitHub Actions Virtual Environments](https://github.com/actions/virtual-environments).
