 ## CI Integration
 
+Tart already powers several CI services mentioned above including our own [Cirrus CI](https://cirrus-ci.org/guide/macOS/) which offers unlimited concurrency with per-second billing.
+For services that haven't leveraged Tart yet, we offer fully managed runners via a monthly subscription.
+*Cirrus Runners* is the fastest way to get your current CI workflows to benefit from Apple Silicon hardware. No need to manage infrastructure or migrate to another CI provider.
+Please read down below about currently supported services.
+
+### Managed runners for your CI-as-a-service
+
+At the moment Cirrus Runners only supports GitHub Actions, but we are actively working on adding more options.
+Please [email us](mailto:hello@cirruslabs.org) if you are interested in a particular one.
+
+#### GitHub Actions
+
+Configuring Cirrus Runners for GitHub Actions is as simple as installing [Cirrus Runners App](https://github.com/apps/cirrus-runners).
+After successful installation and subscription configuration, use any of [Ventura images managed by us](https://github.com/cirruslabs/macos-image-templates) in `runs-on`:
+
+```yaml
+name: Test Suite
+jobs:
+  test:
+    runs-on: ghcr.io/cirruslabs/macos-ventura-xcode:latest
+```
+
+When workflows are executing you'll see Cirrus on-demand runners on your organization's settings page at `https://github.com/organizations/<ORGANIZATION>/settings/actions/runners`.

+
+### Self-hosted CI
+
 Tart itself is only responsible for managing virtual machines, but we've built Tart support into a tool called Cirrus CLI
 also developed by Cirrus Labs. [Cirrus CLI](https://github.com/cirruslabs/cirrus-cli) is a command line tool with
 one configuration format to execute common CI steps (run a script, cache a folder, etc.) locally or in any CI system.

 [Cirrus CI](https://cirrus-ci.org/) already leverages Tart to power its macOS cloud infrastructure. The `.cirrus.yml`
 config from above will just work in Cirrus CI and your tasks will be executed inside Tart VMs in our cloud.
 
 **Note:** Cirrus CI only allows [images managed and regularly updated by us](https://github.com/orgs/cirruslabs/packages?tab=packages&q=macos).

 In many cases there is a need to retrieve particular files or a folder from within a Tart virtual machine.
 For example, the below `.cirrus.yml` configuration defines a single task that builds a `tart` binary and
