Submitting a Plugin

Hi,

I have written and submitted a plugin. For a while, it showed as [approved] on my developer page. I received an email showing my repository subversion link.

I’m stuck. How do I upload the files to the subversion? I know it says to use your wordpress username and pass, but I see nowhere to input this information.

Do I have to download software to communicate with the subversion?

I’m new to submitting a plugin, but fairly savvy with code.

Thanks.
