Here's the transcript for the video:

SilverStripe is an open source content management system or CMS. In this video is a guide to installing SilverStripe for newcomers to web development.

SilverStripe is a web application so it doesn’t run directly on your computer. You need to install a web server and database first before you can run it on your machine. We are showing you this process on a freshly built Wndows Seven system, but the same process has been tested on windows XP and the principles apply no matter what computer you are using.

We’ll start by downloading Firefox from getfirefox.com. Using the Firefox web browser will make it easier to follow this guide. We will also need to download and install winzip to open and extract the SilverStripe code in a later step.

The three components required to run SilverStripe are a web server, a database and a scripting language called php. Apache webserver,MYSQL database and the php language are frequently packaged together into something known as an ampstack. Linux users would download an lampstack, Macintosh users a mamp stack and as were working in windows a Wampstack.
We’ve chosen to use wampserver, which we download and run from wampserver.com/en/download. The installer will ask for permission to make changes to the operating system and firewall. Allow these changes and accept the default installation options including the installation directory at c:/wamp.
Your web servers’ root directory will then be located at c:/wamp/www. This corresponds to the address localhost on your web server so to test if your webserver is working properly open up a new browser window and enter the address: local host. If everything is working then you should see this screen.

Now we’re ready to install SilverStripe, we can download the latest version from the SilverStripe.org website and save this archive to our desktop. The file you have downloaded is an archive within an archive, here we use winzip to extract the SilverStripe directory structure. Copy this directory to the webserver’s root and rename it, here we use silverstripe with no capitals, spaces or special characters.

To install SilverStripe we open up Firefox and go to local host/silverstripe. The file install.php will begin to run and you’ll see this screen. To enable the clean installation we have to enable the rewrite module in Apache. So find the wampserver menu in the windows toolbar, left click to bring up the options and then turn on the rewrite module.
