To start off your SVN you need to create a directory on your local computer. In that directory, execute the following:
svn co --username
http://joomlacode.org/svn/ .
This will checkout the empty repository into the directory you created.
Copy the files you want to checkin into this directory.
Then do:
svn add (svn add * to add everything)
Then:
svn commit
And you are done.
See
