Problems with the Guide
If you're having problems with the guide itself, such as missing, incorrect, or confusing content, please raise an issue on YouTrack. If the problem is easily solved, you can also submit a Pull Request.
If you want to report (smaller) issues for a specific page, you can also use Was this page helpful feedback form on the bottom of each page by providing more details after clicking the No button. Please try to be as specific as possible and provide your e-mail address for further questions and getting notified of updates.
If you just want to share feedback on the guide, again, raise an issue, even if it's for a discussion, ideas on improvements or suggestions.
Problems with Code - Support Issues
For questions and problems related to plugin development itself (rather than the content of this guide), you have several options:
#intellij-platform on JetBrains Platform Slack - this chat room is a great place to ask questions about extending JetBrains products, with answers coming from both JetBrains team members and members of the community
Plugin Development Forum - post a message to the support forum. It is regularly updated with answers by JetBrains team members.
Of course, all raised questions will be used to try and improve this guide.
Problems with Products
If you have a problem with an IntelliJ Platform-based product, such as IntelliJ IDEA, WebStorm, Rider, etc., please use any of the regular Product Support channels.
