 ## gitlab runners
 
+### tl;dr
+
+if your key is already on the runners, you can redeploy them with:
+
+```
+$ g clone git@xgitlab.cels.anl.gov:argo/argopkgs.git
+$ cd argopkgs/deployments
+$ nix-shell
+[nix-shell]$ ./deploy-runners.sh
+```
+
+or reboot/restart their gitlab-runner daemon with:
+```
+$ g clone git@xgitlab.cels.anl.gov:argo/argopkgs.git
+$ cd argopkgs/deployments
+$ ./restart-runners.sh
+$ ./reboot-runners.sh
+```
+see the note below about purging IPs from gitlab in case you do reboot them.
