 > IMPORTANT: Building your own runner is critical for the dev inner loop process when contributing changes.  However, only runners built and distributed by GitHub (releases) are supported in production.  Be aware that workflows and orchestrations run service side with the runner being a remote process to run steps.  For that reason, the service can pull the runner forward so customizations can be lost.

 This process will receive any job queued on this repository if the job runs on matching labels (e.g `runs-on: self-hosted`).
 Once a job is received, a `Runner.Listener` starts a new process of `Runner.Worker`.

+_Note: Actions Runner follows a progressive release policy, so the latest release might not be available to your enterprise, organization, or repository yet. 
+To confirm which version of the Actions Runner you should expect, please view the download instructions for your enterprise, organization, or repository.

 ## Windows x64
 We recommend configuring the runner in a root folder of the Windows drive (e.g. "C:\actions-runner"). This will help avoid issues related to service identity folder permissions and long file path restrictions on Windows.
