+## Quickstart - Standalone Node
+
+###Login
+Log in into the Circle website with admin (the site is accessable on the 443 port). Name and password is in the `salt/pillar/installer.sls`.
+
+### Create Node
+To run virtual machines, we need to create nodes - and add to the system. Click on the new icon in the dashboard, Nodes menu.
+
+####Configure Node
+
+To standalone configuration, type the current machine's hostname to Host/name, MAC address to Host/MAC, IP to HOST/IP. Choose managed-vm as VLAN.
+
+####Activate Node
+
+Click on the 'Activate' icon to use the Node.
+
+### Start Virtual Machine
+
+To create new Virtual Machine, we use Templates - images based on previously saved VMs. Currently we haven't got any template - so let's create a new one. Click on Templates/new icon and choose 'Create a new base VM without disk'.
+
+#### Configure Template
+
+Set name, CPU and RAM settings, architecture. Check in the boot menu box, select network and lease, write down, which operating system will you use. Finally, create a template.

+Currently we don't have any disks attached to our VM. To add, click on the Resources menu, 'create disk' icon, set the name and size.

+
+#### Attach ISO
+
+To install an OS, we can use ISO images, to boot from. Click on 'download disk' and type the ISO's URL.

+Finally, we can run the machine. Click on 'deploy' and start it. You can choose, on which node do you want to run.
