+# Reconfigurator
+
+**Reconfigurator** is a project and control plane facility for dynamically reconfiguring the software running on the Oxide rack.  This will be used for a variety of use cases:
+
+* Adding, removing, or replacing sleds (gracefully or otherwise)
+* Upgrading any Oxide-delivered software (see below)
+* Scale-up and scale-down of control plane services
+* Automated response to hardware failure
+
+For those with access (primarily, Oxide employees), see:
+
+* [RFD 418 Towards automated system update](https://rfd.shared.oxide.computer/rfd/418).
+* [Reconfigurator GitHub Project](https://github.com/orgs/oxidecomputer/projects/44?pane=info).
