    5 === Preparations ===
    6 Before you can complete any of the tutorials, you will need to have to do the following:
    7  1. [[CollapsibleStart(Make a reservation)]][[Include(Documentation/Scheduler)]][[CollapsibleEnd]]
    8  1. [[CollapsibleStart(Login into reserved domain)]][[Include(Documentation/Short/Login)]][[CollapsibleEnd]]
    9  1. [[CollapsibleStart(Check the status)]][[Include(Software/cOMF/eStat)]][[CollapsibleEnd]]
    10 
    11 === Managing Nodes ===
    12  * [[CollapsibleStart(How to load (install) a disk image on a set of nodes)]] [[Include(Documentation/Short/LoadImage)]][[CollapsibleEnd]]
    13  * [[CollapsibleStart(How to save an existing disk image from one node)]] [[Include(Documentation/Short/SaveImage)]][[CollapsibleEnd]]
    14  * [[CollapsibleStart(How to switch On/Off a set of nodes)]][[Include(Tutorial/HowToSwitch)]][[CollapsibleEnd]]
     8A typical experiment requires the following six steps:
     9 1. [[CollapsibleStart(Create resource reservation")]][[Include(Documentation/Short/CreateRes)]][[CollapsibleEnd]]
     10Reserve a set of nodes/resources from a domain to run the experiment on.
     11 2.  [[CollapsibleStart(Login into reserved domain: "ssh username@sb1.orbit-lab.org")]][[Include(Documentation/Short/Login)]][[CollapsibleEnd]]
     12Access the corresponding domain console.
     13 3.  [[CollapsibleStart(Load an image on the nodes: "omf load -i baseline.ndz -t all")]] [[Include(Documentation/Short/LoadImage)]][[CollapsibleEnd]]
     14Install an image on the hard disks of the nodes. After imaging the nodes are '''turned off automatically'''.
     15 4. [[CollapsibleStart(Turn the nodes on: "omf tell -a on -t all")]][[Include(Documentation/Short/TellOn)]][[CollapsibleEnd]]
     16Turn the nodes back on to run the experiment (give them some time and check their status with '''omf stat''' before proceeding).
     17 5. [[CollapsibleStart(Execute the experiment: "omf exec test:exp:tutorial:hello-world-wireless -- --res1 node1-1.sb1.orbit-lab.org --res2 node1-2.sb1.orbit-lab.org")]][[Include(Software/cOMF/aExec)]][[CollapsibleEnd]]
     18Run the experiment (in this case execute "Hello World" built in experiment).
     19 6. Analyze the results
     20Use various tools to analyze the results.
     21 7. (optionally) Save the image [[CollapsibleStart(Save Image with omf: "omf save -n node1-1.sb1.orbit-lab.org")]] [[Include(Documentation/Short/SaveImage)]][[CollapsibleEnd]]
     22If you did something to the image definitely '''save it before the end of your time slot'''!
