| In install4j's main window, there is always one project open at a time. Projects are saved to disk as separate project files with the extension `.install4j`. In a single project, you define the distribution of one application. This includes the definition of: a distribution tree of files and directories What files do you want to distribute? one or several application launchers What are your main classes? the screens and actions in the GUI installer How should your installer look like and what should it do? one or serveral media files What are your target platforms? The configuration steps of the install4j main window lead you step by step through these definitions.

| Projects can be created, saved and opened from install4j's menu bar and tool bar. In addition, you can pass the name of a project file as a command line parameter to install4j to open it on startup.

| In most text fields, you can use variables to internationalize or customize your project.

| Projects can be printed by generating a project report and printing it from your browser.

| Once a project is fully defined, you can build the media files.
