Continua allows you to specify dynamic objects and variables that are then given values when a build is executed. Dynamic objects and expressions are registered with surrounding $ symbols. In the image below you can see that specifying $Source.$ displays a dropdown that lists all the repositories that can be accessed from this configuration. At the moment we only have our Fluent NHibernate repository, however any other repositories that may have been created will also display in this list. So by setting the project file to $Source.Fluent_Nhibernate$, we are pointing Continua to our Fluent_NHibernate repository. If you called your repository a different name then this property will need to reflect the new name. ie. $Source.<repo_name>$
Anything that follows $Source.Fluent_Nhibernate$ refers to the file structure of the repository itself. So by specifying /src/Examples.FirstProject/Examples.FirstProject.csproj we are telling Continua to get the Examples.FirstProject.csproj file from the src/Examples.FirstProject folder of the repository. On the GitHub Fluent NHibernate page you can see the project's repository structure. In the two images below, you can see how we point to the .csproj file in Continua CI and how the project's file structure looks over at GitHub.
