There are several resources for developers to learn more about TiddlyWiki and to discuss and contribute to its development.

• tiddlywiki.com/dev is the official developer documentation
• Get involved in the development on GitHub
  • Discussions are for Q&A and open-ended discussion
  • Issues are for raising bug reports and proposing specific, actionable new ideas
• The older TiddlyWikiDev Google Group is now closed in favour of GitHub Discussions but remains a useful archive: https://groups.google.com/group/TiddlyWikiDev
  • An enhanced group search facility is available on mail-archive.com
• Follow @TiddlyWiki on Twitter for the latest news
• Chat at https://gitter.im/TiddlyWiki/public (development room coming soon)
