JetBrains tools like IntelliJ IDEA are powerful developer productivity tools. What is the best way to learn how to harness that power?

You can find useful information on our Twitter page , or our product blog . Or videos on our YouTube channel . Plus, the documentation is always there to help.

We have also created the IntelliJ IDEA Guide, a collection of bite-sized visual resources, organized to help spark your learning. We hope it helps you get into the flow and excel at what you do.

Sharing feedback and contributing

The IntelliJ IDEA Guide is also an open project, with a repository in GitHub that hosts all the content. We write all the content in Markdown and render a static site. If you'd like to contribute to it, please refer to the README for more information.
