-# Automate Configuring Self-Hosted Runners
-
-
-## Export PAT
-
-Before running any of these sample scripts, create a GitHub PAT and export it before running the script
-
-```bash
-export RUNNER_CFG_PAT=yourPAT
-```
-
-## Create running as a service
-
-**Scenario**: Run on a machine or VM (not container) which automates:
-
- - Resolving latest released runner
- - Download and extract latest
- - Acquire a registration token
- - Configure the runner
- - Run as a systemd (linux) or Launchd (osx) service
-
-:point_right: [Sample script here](../scripts/create-latest-svc.sh) :point_left:
-
-Run as a one-liner. NOTE: replace with yourorg/yourrepo (repo level) or just yourorg (org level) 
-```bash
-curl -s https://raw.githubusercontent.com/actions/runner/automate/scripts/create-latest-svc.sh | bash -s yourorg/yourrepo
-```
-
-## Uninstall running as service 
-
-**Scenario**: Run on a machine or VM (not container) which automates:
-
- - Stops and uninstalls the systemd (linux) or Launchd (osx) service
- - Acquires a removal token
- - Removes the runner
-
-:point_right: [Sample script here](../scripts/remove-svc.sh) :point_left:
-
-Repo level one liner.  NOTE: replace with yourorg/yourrepo (repo level) or just yourorg (org level) 
-```bash
-curl -s https://raw.githubusercontent.com/actions/runner/automate/scripts/remove-svc.sh | bash -s yourorg/yourrepo
-```
-
-### Delete an offline runner
-
-**Scenario**: Deletes a registered runner that is offline:
-
- - Ensures the runner is offline
- - Resolves id from name
- - Deletes the runner
-
-:point_right: [Sample script here](../scripts/delete.sh) :point_left:
-
-Repo level one-liner.  NOTE: replace with yourorg/yourrepo (repo level) or just yourorg (org level) and replace runnername
-```bash
-curl -s https://raw.githubusercontent.com/actions/runner/automate/scripts/delete.sh | bash -s yourorg/yourrepo runnername
