= Creating A GEMINI Slice for ''Getting Started with GENI Part 3'' =

Part 3 of this tutorial track will be using a 5-node topology for exercises in configuring and using GEMINI instrumentation and measurement tools. [[BR]]
If you will be attending this tutorial, it will help to create your slice and sliver ahead of time by following these instructions.

== 1.  Create your slice ==

In the GENI Portal, create a slice in the GEC17 project using a slice name starting with GEM (for example ''GEMmyname''). 

== 2.  Add resources to your slice ==

Click on the "Launch Flack" button for your slice and create the topology shown in the following figure.  [[BR]]

Use resources from the aggregate assigned to you:
[[BR]][[BR]][[BR]][[BR]][[BR]]



The rspec for this topology is also given [http://groups.geni.net/geni/wiki/GEMINI/Tutorial/GEC17/CreatingGEMINISlice#Samplerspec below] in case you prefer to import the rspec.
