Creating a GIT Trunk Using GIT SVN From a SVN repo

I'm currently climbing the learning curve on both GIT and SVN. I've been tasked with figuring out how to migrate our current repos from SVN, with history, to a new GIT Trunk repo. I've experimented with the Git Extension GUI and the Git Bash interface, but my exported GIT repo is empty. The originating SVN repo doesn't have a TRUNK directory, so I thought maybe branching or migrating to a SVN report with a TRUNK and then using GIT SVN to migrate might work. I'm looking for specific suggestions on how I can proceed.  Cheers!  [email]Brandon.Forest@blueshieldca.com[/email]
