 ## Prerequisites
 
-There are several preparation work that need to be done before deploying SD-Fabric.
-1. All switches have been provisioned with Docker and Kubernetes
-2. All switches have been configured as special Kubernetes nodes
-3. Prepare ONOS network config
-4. Prepare Stratum chassis config for each switch
-
-Please refer to step 1 to 4 in [SD-Fabric deployment guide](https://docs.sd-fabric.org/master/deployment.html)
-for prerequisites, and come back here for the rest of the installation instructions.

 1. **Clone SD-Fabric Helm chart**
 
     ```bash
+    cd $HOME/
     git clone ssh://gerrit.opencord.org:29418/sdfabric-helm-charts
-    cd sdfabric-helm-charts/sdfabric
+    cd $HOME/sdfabric-helm-charts/sdfabric
     ```

-3. **Prepare your Helm value**
+## Fully virtual Installation 
+
+This section allows you to deploy a fully virtual system with Kind, Mininet and ONOS on you devlopment machine. 
+The topology is a custom 2x2 leaf spine topology, defined in mininet in the 
+[topo-leafspine.py](https://github.com/opencord/helm-charts/blob/master/mininet/toposcripts/topo-leafspine.py) and described 
+in ONOS in the `dev-values.yaml` `netcfg` section. 
+
+**Note** This section is based on docker and kind, please ensure to have both installed in your environment.
+Also ensure to give enough resources to your docker env. A suggestion is 16GB of ram, 12 cores, 2 GB of swap.
+
+### Mininet and Fabric Deployment
+
+1. **Download the mininet helm charts**
+
+   ```bash
+   cd cd $HOME/
+   git clone https://gerrit.opencord.org/helm-charts
+   cd $HOME/helm-charts/mininet
+   ```
+
+2. **Update Helm dependencies**
+
+    ```bash
+    helm dep update
+    ```
+
+3. **Deploy a kind cluster**
+
+   ```bash
+   cd $HOME/sdfabric-helm-charts/sdfabric
+   kind create cluster --config $HOME/sdfabric-helm-charts/configs/3-node-cfg.yaml
+   kubectl taint nodes --all node-role.kubernetes.io/master-
+   ```
+
+4. **Deploy Mininet**
+   
+   ```bash
+   cd $HOME/helm-charts/mininet
+   helm install -n sdfabric --create-namespace -f sdfabric-values.yaml mininet .
+   ```
+   
+5. **Deploy Sd-Fabric**
+
+   ```bash
+   cd $HOME/sdfabric-helm-charts/sdfabric
+   helm install -n sdfabric --create-namespace -f dev-values.yaml sdfabric .
+   ```
+
+6. **Verify the installation**
+    ```bash
+    helm -n sdfabric ls
+    ```
+
+7.  **Uninstall**
+    ```bash
+    helm -n sdfabric delete sdfabric
+    helm -n sdfabric delete mininet
+    ```
+### Useful Commands
+
+Attach to Mininet
+
+   ```bash
+   kubectl attach -it -n sdfabric <mininet pod name> 
+   ```
+   Example of pod name: mininet-578d9575d4-xdtb2
+
+SSH into ONOS
+   Pick the instance you prefer (if you deployed more than 1)
+   ```bash
+   kubectl -n sdfabric exec -it sdfabric-onos-classic-0 -- bash /root/onos/apache-karaf-4.2.14/bin/client
+   kubectl -n sdfabric exec -it sdfabric-onos-classic-1 -- bash /root/onos/apache-karaf-4.2.14/bin/client
+   kubectl -n sdfabric exec -it sdfabric-onos-classic-2 -- bash /root/onos/apache-karaf-4.2.14/bin/client
+   ```
+
+### Parameters
+
+If you'd like to modify the number of ONOS instances and Atomix (1 and 1 by default), you can do so by changing the
+parameters in the `dev-values.yaml` file.
+
+`onos-classic.atomix.replicas` for Atomix.
+
+`onos-classic.replicas` for ONOS.
+
+If you want to change the topology entirely:
+
+- please write a new `topo.py` file in the `mininet` helm chart 
+- specify it as a parameter it in the `sd-fabric-values.yaml` file under `topoScript`. 
+- write a new `netcfg` for ONOS based on the new `topo.py` file
+- Insert it under `onos-classic.netcfg` in `netcfg-leafspine.yaml` in the sdfabric helm chart. 
+
+## Hardware Installation
+
+### Prerequisites
+
+There are several preparation work that need to be done before deploying SD-Fabric.
+1. All switches have been provisioned with Docker and Kubernetes
+2. All switches have been configured with SD-Fabric specific taints and labels
+3. Prepare ONOS network config
+4. Prepare Stratum chassis config for each switch
+
+These steps assume you have already deployed a three node kubernetes cluster 
+and have management connectivity to a fully sd-fabric compliant fabric.
+Please refer to step 1 to 4 in [SD-Fabric deployment guide](https://docs.sd-fabric.org/master/deployment.html)
+for prerequisites, and come back here for the rest of the installation instructions.
+
+### Hardware deployment 
+
+1. **Prepare your Helm value**
 
     You can modify existing `values.yaml` directly, but we recommend composing another value file `myvalues.yaml` using `values.yaml` as an example.
