+# Docker Open vSwitch for GNS3
+
+This creates a container for using Open vSwitch in GNS3.
+
+This container supports ethernet interfaces and comes
+with bridges from br0 to br3.
+
+By default, all interfaces are connected to br0.
+
+If you set the `MANAGEMENT_INTERFACE` environment variable to
+an interface name, that interface will not be connected to br0.
+
+
+## Building the container
+
+```
+docker build -t gns3/openvswitch .
