-## Using on GHES
-
-GitHub Runners come [pre-installed with Docker Buildx](https://github.com/actions/runner-images/blob/main/images/linux/Ubuntu2204-Readme.md)
-following your virtual environment. If you specify a version or `latest` of
-Docker Buildx in your workflow, the version will be downloaded from [GitHub Releases in `docker/buildx`](https://github.com/docker/buildx/releases)
-repository. These calls to `docker/buildx` 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 `github_token` input for the action:
-
-```yaml
-uses: docker/setup-buildx-action@v2
-with:
-  github_token: ${{ secrets.GH_DOTCOM_TOKEN }}
-  version: v0.10.1
-```
-
-If the runner is not able to access `github.com`, it will take the default one
-available on the GitHub Runner or runner's tool cache. See "[Setting up the tool cache on self-hosted runners without internet access](https://docs.github.com/en/enterprise-server/admin/github-actions/managing-access-to-actions-from-githubcom/setting-up-the-tool-cache-on-self-hosted-runners-without-internet-access)"
