I read the Git manual, FAQ, Git - SVN crash course, etc. and they all explain this and that, but nowhere can you find a simple instruction like:
SVN repository in: <
Magic:
$ git svn clone http://svn/repo/here/trunk
Git and SVN operate very differently. You need to learn Git, and if you want to track changes from SVN upstream, you need to learn git-svn. The git-svn main page has a good examples section:
git-svn
$ git svn --help
