Using Versions (SVN client) - i don't get it

[gameover]

Hi,
I've never used version control stuff before, but seeing as i do run and update websites i probably should.

I currently use Coda, and have Versions installed, and after following a tutorial i've got dropbox set up so versions saves the svn database stuff on dropbox, so i can use it on other computers.

I don't really get the process though. Right now, i login (via ftp/sftp) in coda, double click the file, edit it (in coda still), cmd + s, and it saves it.

If i want to use version control, would i have to do that same thing, but after i've made each change, copy it over to the folder i use for the svn database (on my dropbox "drive")? is there any way to just automate it?

thanks

you should have one svn repository.
use tortoisesvn to get a local copy into your chosen folder, then work directly on that.

But what if the site has 100s of files, yet i only need to edit one or two, this will mean downloading 100s of files every time i want to edit something?
