A Divio application is defined by the code in its Git repository.
When a new application is created on the Control Panel, some pre-defined application types can also be used (based on a combination of Stack, Additional components and Additional Boilerplate).
Generally, you will select Build your own and construct your own Dockerfile.
We also provide some pre-built application templates for Aldryn Python, Node, PHP, Java and others (see :ref:`below <project-creation-pre-built>`).
Additional components may be available, depending on the selected Stack.
For the Aldryn Python platform, examples include Django and django CMS; for the PHP platform, Laravel and Symfony, and so on.
Additional Boilerplates may be available, depending on the selected Additional components.
Boilerplates provide additional functionality baked into the application. For example, an Aldryn Python/django CMS application can be launched with Boilerplates for Bootstrap, Foundation and other technologies.
By default, your application will use Divio's own private Git server. Alternatively you can select a Git provider of your choice. You can :ref:`migrate an application from our Git server to an external provider at any time <configure-version-control>`.
For a quick start, use Divio's Git server.
We also provide some optional ready-to-go definitions for a quick start. For example:
- Stack: Aldryn Python
- Additional components: django CMS
- Additional Boilerplate: HTML5
It's important to understand that these pre-built application templates are simply there to provide you with a quick way to get started with a particular stack. They don't prevent you from adding other components.
