+In the single pod installation guide, we discuss how to deploy the Tricircle in
+one single pod with DevStack. Besides the Tricircle API and the central Neutron
 server, only one pod(one pod means one OpenStack instance) is running. Network
 is created with the default network type: local. Local type network will be only
 presented in one pod. If a local type network is already hosting virtual machines
 in one pod, you can not use it to boot virtual machine in another pod. That is
 to say, local type network doesn't support cross-pod l2 networking.
