New User of InstaDMG need help please

Hi All, I am new at using InstaDMG, and need help pretty much from the beginning. I have downloaded and installed the 1.5rc1, but will be using this for a 10.6.2 image to begin with. So I tried to run the "svn checkout http://instadmg.googlecode.com/svn/trunk/ instadmg-read-only" from terminal and it gave me errors: svn: PROPFIND request failed on '/svn/trunk' svn: PROPFIND of '/svn/trunk': Could not resolve hostname `instadmg.googlecode.com': Host not found (http://instadmg.googlecode.com) I have read the pdf file based for 1.4b3, which I am assuming is still current. I have moved the .PKG file for Mac OSX 10.6 from the hidden Packages folder on the OSX installer DVD to the Base OS Folder(I read that it needs to be a DMG for the Base OS, so I am not sure if what I have currently would work). I moved the MacOSXUpdCombo10.6.2.dmg into a folder called "01" under the BaseUpdates folder and I moved a firefox .dmg into a "01" folder under CustomPKG. I have not tried to do anything yet in running the command just planning and putting files in folders. Is what I did correct so far? What do I need to do next? How can I get the latest version, as I understand that there is a bug in 1.5rc1 for 10.6? How do I use the other features InstaUp2Date? I will not have any local users except for an admin account which would be the same everywhere, so would I need to do something for that? If there is a good place to point me for this information, please let me know. I have not been able to find enough, except for the command above to do that checkout, which does not seem to work. Thanks, Steven Stuart
