Configuring Project and IDE Settings
Project settings refer to a set of preferences related to resources, file colors, version control options, code styles, and so on. Project settings are stored with each specific project as a set of xml files under the .idea folder.

The level of a template project. The settings defined for a template project, apply to any project you create.
The project level. Settings defined on this level apply to the current project only.
