An SQL CE database is included in this project, and will be used by default. However, if you wish to use the code with a database of your own choice, simply clear the <connectionStrings> in web.config and set umbracoConfigurationStatus under <appSettings> to "". Running the solution will then prompt a new installation where you can specify a custom database.
You can then install the provided 24days_content.zip (via Developer > Packages > Install Local) to get all the document types, templates, and content.
