 Tinkerbell is a bare metal provisioning engine.
 It’s built and maintained with love by the team at Packet.
 
-This repository is [Maintained](https://github.com/packethost/standards/blob/master/maintained-statement.md) meaning that this software is supported by Packet and its community - available to use in production environments.
+This repository is [Experimental](https://github.com/packethost/standards/blob/master/experimental-statement.md) meaning that it's based on untested ideas or techniques and not yet established or finalized or involves a radically new and innovative style! This means that support is best effort (at best!) and we strongly encourage you to NOT use this in production.
