Run IntelliJ IDEA for the first time
When you run IntelliJ IDEA for the first time, some steps are required to complete the installation, customize your instance, and start working with the IDE.
How to run
Find IntelliJ IDEA in the Start menu or use the desktop shortcut, if it was created during installation. You can also run idea.bat in the installation directory under bin.
Run the IntelliJ IDEA app in the Applications directory, from Launchpad, or from Spotlight.
Run the idea.sh shell script in the installation directory under bin. You can also use the desktop shortcut, if it was created during installation.
For information about running IntelliJ IDEA from the command line, see Command-line interface.
Select the user interface theme
Select whether you want to use the default Darcula or Light theme.
Create launcher script
For macOS and Linux users, IntelliJ IDEA suggests to create a script for opening projects and files from the command line.
Windows users can run the executable file in the installation directory.
For more information, see Command-line interface.
Disable unnecessary plugins
IntelliJ IDEA includes plugins that provide integration with different version control systems and application servers, add support for various frameworks and development technologies, and so on. To increase performance, you can disable plugins that you do not need. If necessary, you can enable them later in the Settings/Preferences dialog Ctrl+Alt+S under Plugins. For more information, see Manage plugins.
You can click the Disable All link for each group of plugins to disable them all, or Customize to disable individual plugins in the group.
Download and install additional plugins
If necessary, download and install additional plugins that are not bundled with the IDE from the IntelliJ IDEA plugins repository.
