hello

just installed Concrete5 and have big plans for it :)
Any way I´m only expierienced with html and css (and a little bit of databases and cpanel etc hosting isssues)

I installed it in a subcategory on my site like this:
http://www.mysite.com/concrete5

can I put and edit files on
http://www.mysite.com/
http://www.mysite.com/cats
http://www.subdomain.mysite.com/

on the public root I would like to make an index file
and on a subdomain I would like to give my customers their own "site" with concrete5 admin just for that subcategory

I am very enthusiastic with this and need some support to get started. Tanks
