+3.Download slave.jar and put it into $HOME directory of jenkins user
+4.Your slave has been configured in OPNFV Jenkins
+5.Obtain slave's token from Linux Foundation Helpdesk
+Consult wiki : https://wiki.opnfv.org/wiki/jenkins#how_to_connect_servers_from_labs_to_opnfv_jenkins
+
+Follow steps below to launch your slave to OPNFV Jenkins:
+1. cp jenkins-slave.init /etc/init.d/jenkins-slave
+2. chmod +x /etc/init.d/jenkins-slave
+3. define $SLAVENAME&$TOKEN in config file(jenkins-slave)
+4. cp jenkins-slave /etc/default/jenkins-slave
