All settings are defined in the python module project.settings. banana first loads project.settings.base followed by project.settings.local. When you start using banana for the firs time, there will be no local file. You should copy project.settings.local_example to project.settings.local and adjust it to your environment. The base should contains all settings which are required by Banana and you should not modify this file. You should override, append or define new settings variables in local.
