The latest installation files can always be found at: http://kooboo.codeplex.com. The file name is usually "kooboo_CMS.zip". Download and unzip it to a local folder.
Using Visual Studio.NET
The Koboo_CMS folder contains a standard ASP.NET MVC website. First start up your Visual Studio.NET 2010/2012. Then click on File and select Open --> Web Site. Now you can start using Kooboo CMS.
Alternatively, you can set up a website with IIS and print the root directory to the Kooboo_CMS folder. Make sure that your website can support ASP.NET MVC. In IIS 5 or 6, you might want to map the wildcard (*) extension to the ASP.NET ISAPI filter to make sure that ASP.NET MVC runs smoothly.
If you are setting up Kooboo CMS manually, make sure that IIS user has the read/write/execute rights to the CMS_Data folder.
Open your favorite browser and visit the website you just created. You can start using the Kooboo CMS now. Default username/password is: admin/admin
