+# Gossip Registry
+
+Gossip is a registry plugin for go-micro which uses hashicorp/memberlist to broadcast registry information
+via the SWIM protocol.
+
+## Usage
+
+Import the plugin as per usual
+
+```go
+import _ "github.com/micro/go-plugins/registry/gossip"
+```
+
+On startup you'll see something like
+
+```go
+2016/06/19 14:05:43 Local memberlist node 127.0.0.1:45465
+```
+
+To join this gossip ring use `--registry_address 127.0.0.1:45465` when starting other nodes
