 # Architecture Decision Records
 
-The directory [adr](adr) hold Architecture Decision Records that document major decisions made
-in the design of the NATS Server.
-
-A good intro to ADRs can be found in [Documenting Architecture Decisions](http://thinkrelevance.com/blog/2011/11/15/documenting-architecture-decisions) by Michael Nygard.
-
-## When to write an ADR
-
-Not every little decision needs an ADR, and we are not overly prescriptive about the format.
-The kind of change that should have an ADR are ones likely to impact many client libraries
-or those where we specifically wish to solicit wider community input.
-
-## Format
-
-The [adr-tools](https://github.com/npryce/adr-tools) utility ships with a template that's a
-good starting point. We do not have a fixed format at present.
-
-## ADR Statuses
-
-Each ADR has a status, let's try to use `Proposed`, `Approved` `Partially Implemented`, `Implemented` and `Rejected`.
+The NATS ADR documents have moved to their [own repository](https://github.com/nats-io/nats-architecture-and-design/)
