Hello, I am very new to Silverstripe and if anything, the hardest part was finding stuff to put on my site since it's so easy to use. :)
I am wondering about updating though. First where do I find the update in the admin panel? Second how do I find the version number as I just installed whatever version was in my website's control panel. I looked at the bottom of my page and it was missing. If I go to /test.php though it shows string(9) "3.0.x-dev"
I love the simple skin by the way. Though I had to hack it a bit to put a small logo in. Would updates wipe that out? If I copied the skin then modified it the site showed some default blur bar with the menu missing.
1) The system doesn't currently have a UI based update tool. With 3.0 it introduced a composer support (http://getcomposer.org/) which might make a UI for updates 'possible' but it's not something the core team are interested in (updates should be done by developers, not CMS users!)
2) Version number is shown in the CMS if you hover over the SilverStripe logo on the left. If you use composer to download / manage your SilverStripe installation then you can use that to tell you what version you have.
3) You can customize the CMS CSS by defining a custom CSS file - LeftAndMain::require_css('path/to/your/css.css') then but any customisations in that CSS file.
