Checking out using TortoiseSVN?
- First, navigate to the following folder (or another location, if you prefer):
C:\\Program Files\Common Files\Cycling'74
- Create a new folder named Jamoma, and open it.
- Right click to bring up the contextual menu, and select "SVN Checkout...":

- In the dialog box, use this URL:
https://jamoma.svn.sourceforge.net/svnroot/jamoma/trunk/Jamoma/
- Hit return for the next dialog box that comes up.
From, now on you will be able to do pretty much anything using the contextual menu.
