Project settings
Project settings apply to the current project only. They are stored in the .xml format together with other project files in the .idea directory. Project settings can include VCS configuration, code style options, the list of language inspections, and other settings.
To configure project settings, select on macOS or on Windows and Linux from the main menu. Alternatively, you can press Control+Alt+S to show the IDE settings.
In the Settings dialog, project settings that apply only to the current project are marked with the 
icon. Other settings are global and apply to all existing projects.
If you want to share project settings between already existing projects, you can use the Settings Sync plugin. You can also export the settings to a ZIP archive and import it later to other IDE instances.
Default settings for new projects
You can configure project settings not only for the current project, but for all projects that you will create later. This means that you can set the new default settings for your projects.
