Downloading ScratchR
Installing git
First of all, let's navigate to the download page. The link for it will vary depending on your operating system. Note that this guide expects you to be on Windows.
Run the installer to install git
Cloning ScratchR
Navigate to C:\XAMPP\, delete htdocs, create a new folder with that name and open it.
Next, open up CMD like with memcached, but this time, run this command:
git svn clone https://subversion.assembla.com/svn/scratchr/
In the next steps, if I mention anything under \app, it's inside C:\XAMPP\htdocs\scratchr\app
