== 1. Design the Experiment ==
In this exercise we will convert the [wiki:GENIExperimenter/Tutorials/RunHelloGENI HelloGENI exercise] install script into an Ansible playbook.
You may want to quickly run the [wiki:GENIExperimenter/Tutorials/RunHelloGENI HelloGENI exercise] to see how it works.

For reference here is the install script pruned to only handle Apache 2.2 (the original handles multiple versions of Apache).
