 Guides and a service for network booting and provisioning CoreOS clusters on virtual or physical hardware.
 
+**Announcement**: coreos-baremetal and `bootcfg` are being renamed to CoreOS `matchbox`, which will be reflected in v0.5.0. Please see [CHANGES](CHANGES.md) or [#400](https://github.com/coreos/coreos-baremetal/issues/400). If you're looking for older docs, be sure to use the branch/tag switcher.

+### Enterprise
+
+[Tectonic](https://coreos.com/tectonic/) is the enterprise-ready Kubernetes offering from CoreOS (free for 10 nodes!). The [Tectonic Installer](https://tectonic.com/enterprise/docs/latest/deployer/platform-baremetal.html) app integrates directly with `matchbox` through its gRPC API to provide a rich graphical client for populating `matchbox` with machine configs.
