+
+## Quickstart
+
+This is a quickstart guide of howto use this *LabInstance to deploy Linux systems*
+
+### HowTo use it
+
+
+### Default Configuration 
+
+- Working Directory
+
+> /project
+
+- Default user
+
+> docker
+
+- Default password
+
+> docker
+
+- Default password4root
+
+> pass
+
+
+####  Find lab workers
+
+
+> ifconfig
+>
+> nmap -sP 172.130.0.0/24
+>
+> or
+>
+> /project/bin/swarmlab-nmap
+
+
+#### connect to workers
+
+```bash
+ ssh docker@[IP]
+```
+
+
+#### Create hosts file
+
+
+```bash
+/project/bin/swarmlab-nmap > /project/hosts
+```
+
+
+---
+**NOTE:** copy files to all clients
+
+```bash
+while read -r line; 
+ do 
+   scp /project/file docker@$line:/some_dir/file
+done < /project/hosts
+```
