 We use [Runs-On](https://runs-on.com/) for some actions in the main repository, which run in the ASF AWS account to speed up CI time. In forks, these actions run on the default GitHub runners since forks do not have access to ASF infrastructure.
 
-We also use standard GitHub runners for some actions in the main repository; these are also runnable in forks.
+To configure them, we use the following format:

+This is a conditional expression that uses Runs-On custom runners for the main repository but falls back to the standard GitHub runners for forks. Runs-On configuration follows the [Runs-On pattern](https://runs-on.com/configuration/job-labels/).

+For those actions we also use the [Runs-On action](https://runs-on.com/caching/magic-cache/#how-to-use), which adds support for external caching and reports job metrics:
