<br>
to run the tutorial online (ie via <a href="http://etkhub.ndslabs.org/" rel="noreferrer" target="_blank">http://etkhub.ndslabs.org/</a>) you do<br>
not need to install any software. The "Prerequisites" section is only<br>
used when you want to run the tutorial on your own laptop. The section<br>
talking about xcode in particular is only used on OSX systems (Macs).<br>
<br>
Yours,<br>
