IntelliJ IDEA displays the Welcome screen when no project is opened. From this screen, you can quickly access the main sections of IntelliJ IDEA. The Welcome screen appears when you close the only opened instance of the project, or you run IntelliJ IDEA for the first time.
Also, use the drop-down arrows () Configure to configure your working environment, and Get Help to open help topics, tips of the day, and default keymap document.
If you have several projects in IntelliJ IDEA, you can see a list of these projects in the left pane of the Welcome screen.
