I've recently downloaded Joomla using an instant download option, and now I'm looking to create my own templates. I went to http://www.siteground.com/tutorials/joomla15/joomla_create_template.htm and am trying to follow the tutorial but I've failed at the first hurdle... where it says:
First, open the "templates" directory in your Joomla installation. Then create a subfolder in it named "tutorial_template". All the files of your template will reside in it.
The problem is I have no clue how to do this, where is the directory to start with? The only thing I know how to get up is the administrator's screen, in which I have to choose one of the stock templates, which would be great if I didn't care about my own designs...but obviously I'm looking to have my own HTML and CSS coding used instead.
How do I find where the folders are and how do I open them?
