DrupalCon sites are simple to build.
For all site functionality we use the COD_support project and it's dependencies.
Each site is responsible for it's own theme. But to aid with ease of installation and updates, we use the drupalcon_base project as a repository for all themes. Each site has a directory, which then contains the base theme used and your sub-theme. See Contribute a DrupalCon theme for more information on how to create your own sub-theme.
If there is additional functionality required, it must be included in the COD project. Because DrupalCon sites share a common code base, we cannot include custom features or modules, they will be over-written.
