+
+## Download and install the latest release
+$ sudo bash -c "$(curl -sL https://get.containerlab.dev)"
+
+## Deploy proposed two SR node scenario
+$ cd ~/tfs-ctrl/hackfest/containerlab
+$ sudo containerlab deploy --topo tfs-scenario.clab.yml
+
+## Access SR Bash
+$ docker exec -it clab-tfs-scenario-srl1 bash
+
+## Acess SR CLI
+$ docker exec -it clab-tfs-scenario-srl1 sr_cli
+
+## Destroy scenario
+$ sudo containerlab destroy --topo tfs-scenario.clab.yml
+
+## Install gNMIc
+$ sudo bash -c "$(curl -sL https://get-gnmic.kmrd.dev)"
+
+## gNMI Capabilities request
+$ gnmic -a clab-srlinux-srl1 -u admin -p NokiaSrl1! --skip-verify capabilities
+
+## gNMI Get request
+$ gnmic -a clab-srlinux-srl1 -u admin -p NokiaSrl1! --skip-verify -e json_ietf get --path /system/name/host-name
+$ gnmic -a clab-srlinux-srl1 -u admin -p NokiaSrl1! --skip-verify -e json_ietf get --path /interface[name=mgmt0]
+
+## gNMI Set request
+$ gnmic -a clab-srlinux-srl1 -u admin -p NokiaSrl1! --skip-verify -e json_ietf set --update-path /system/name/host-name --update-value slr11
+
+(we check the changed value) 
+$ gnmic -a clab-srlinux-srl1 -u admin -p NokiaSrl1! --skip-verify -e json_ietf get --path /system/name/host-name 
+
+## Subscribe request
+$ gnmic -a clab-srlinux-srl1 -u admin -p NokiaSrl1! --skip-verify -e json_ietf subscribe --path /interface[name=mgmt0]/statistics
+(In another terminal, you can generate traffic) 
+$ssh admin@clab-srlinux-srl1
+
+
+## Enable OpenConfig data models and set as default:
+$ docker exec -it clab-tfs-scenario-srl1 sr_cli
+# enter candidate
+# system management openconfig admin-state enable
+# system gnmi-server network-instance mgmt yang-models openconfig
+# commit stay
+# quit
