+If you are following on from the Flack tutorial, and the slice you created then has not yet expired, you can reuse the same slice -- skip ahead to the next step.

+Otherwise, you will need to create a new slice, which can be done through the GENI Portal, as follows:

+<p>Next, we will learn about the mechanism Flack had been using when bringing up slivers for us.  Behind the scenes, slivers are described in GENI <b>rspec</b> files, which are relatively simple XML documents precisely describing the components, configurations, and topologies.</p>

You should download this now, and save it where you can get to it with your browser.  If you have time, it is worthwhile inspecting the contents to see the style of rspec files (in this case, another simple sliver consisting of two nodes connected by a single network link).</p>
