The information architecture on this site has serious issues; it's almost impossible to work out. You would really benefit from use cases : someone with no site wants to install Silverstripe, someone with a static site wants to bring that into Silverstripe, someone who is on another CMS wants to move over to Silverstripe. See how your site works from their perspectives.
I currently have a static site I want to bring over to Silverstripe, but I need basic information (such as how to securely install the CMS).
As far as I can tell, the installation needs to occur in a public folder with high permissions ratings. To me, that is far from secure. How do I securely install Silverstripe?
If I install Silverstripe, do I immediately wipe out (some/all/none) of the contents already present, including the current .htaccess file?
On this page here, you say "visit the URL". Which URL is that? Is that set up in the folder-name/install.php page?
Does it matter whereabout in your directory system that you upload and install from? Does it need to be directly from 'www' ('html_public') or can it be higher?
Can you rename the extracted folder name from silverstripe-v2.0 to CMS without causing difficulty to the installation process?
