-How to install demo vm:
+Topology:
 
-- Clone submodules
-```bash
-$ git submodule update --init
-```
+Basically, we emulate SDN-IP topology from [Taiwan NCTU](http://www.nctu.edu.tw/en) peering site.
 
-- Start VM
-```bash
-$ vagrant up
-```
+More information, see our [intro video](https://www.youtube.com/watch?v=a8LR1DyzGY4) or [slide](http://www.slideshare.net/FeiJiSiao/global-sdnip-deployment-at-nctu-taiwan)

-To use:
+Getting started:
+See [Getting Started](https://github.com/sdnds-tw/SDN-IP-Example-VM/wiki/Getting-started)
 
-- Connect to vm via ssh
-```bash
-$ vagrant ssh
-```
-
-- Switch user to root
-```bash
-$ sudo su
-```
-
-- Check cell settings
-```bash
-$ cell
-```
-
-- Start ONOS
-```bash
-$ ok clean
-```
-
-- In ONOS console, start proxyarp and fwd app
-```
-onos> app activate org.onosproject.proxyarp
-onos> app activate org.onosproject.sdnip
-```
-
-- Push SDN-IP network config
-```bash
-$ onos-netcfg $OC1 sdndstw-sdnip.json
-```
-
-- Start demo mininet, let routers exchange their information
-```bash
-$ # For Quagga version
-$ ./sdnip_quagga.py
-
-$ # For GoBGP version
-$ ./sdnip_gobgp.py
-```
-
-- Use ```routes``` command in ONOS console, should get all network routes (might be different between Quagga and GobGP version)
-```bash
-onos> routes
-   Network            Next Hop
-   192.168.4.0/24     192.168.3.11   
-   192.168.5.0/24     192.168.2.11   
-Total IPv4 routes = 2
-
-   Network            Next Hop
-Total IPv6 routes = 0
-```
-
-- In mininet, we can use ```hostname ip route``` command to get routing table in router.
-```bash
-mininet> quagga1 ip route

-- In mininet, we can use host ```khost``` from kreonet to ping ```ahost``` from amlight.
-```bash
-mininet> khost ping -c4 ahost
